Dhat As-Salasil is a spot situated ten days' walk north of Madinah. The Muslims are said to have encamped in a place with a well of water called Salsal, hence the terminology Dhat As-Salasil. In view of the alliance between the Arabian tribes on the borders of Syria and the Byzantines, the Prophet peace be upon him deemed it of top urgency to carry out a wisely-planned manoeuvre that might bring about a state of rapport with those bedouins, and would at the same time detach them from the Byzantines. For the implementation of this plan, he chose 'Amr bin Al-'As, whose paternal grandmother came from Bali, a tribe dwelling in that area. This motive in mind, combined with provocative military movements, by Bani Quda'a, precipitated this preemptive strike which started in Jumada Ath-Thaniya, 8 A.H.

'Amr bin Al-'As was awarded a white flag with a black banner to go with it. He set out at the head of 300 Emigrants and Helpers assisted by a cavalry of 30 men, and was recommended to seek help from Bali, 'Udhra and Balqain tribes. He used to march at night and lurk during the day. On approaching the enemy lines and realizing the large build up of men, he sent for reinforcements from Madinah, and these arrived on the spot headed by Abu 'Ubaidah bin Al-Jarrah leading further 200 men as well as other platoons including Abu Bakr and 'Umar bin Al-Khattab. All of them were given strict orders to cooperate, work in harmony and never leave any area for disagreement. At noon, Abu 'Ubaidah wanted to lead the Muslims in prayer, but 'Amr objected on grounds that the former came only to assist, and leadership in prayer was given to 'Amr.

The Muslim army reached the habitations of Quda'a and penetrated deep in their land, destroyed the enemies and obliged the others to flee for their lives in different directions. At the conclusion of the military operations, a courier was despatched to the Messenger of Allâh peace be upon him to brief him on the developments of events and the ultimate victory achieved.

In Sha'ban month 8 A.H., news reached the Prophet peace be upon him of amassing troops by Bani Ghatfan, still outside the domain of Islam. He urgently summoned Abu Qatadah and sent him at the head of fifteen men to discipline those outlaws. It took fifteen days to teach them an unforgettable lesson. Some were killed, others captured and all their property confiscated.

Ibn Al-Qaiyim described the conquest of Makkah as the greatest one by which Allâh honoured His religion, Messenger, soldiers and honest party. He thereby rescued the Sacred House, whose guidance all people seek. It was the greatest propitious event in heaven and on earth. It was the most significant prelude to a new era that was to witness the great march of Islamization and the entry of people into the fold of Islam in huge hosts. It provided an ever shining face and a most glowing source of inspiration to the whole earth.

According to the terms of the treaty of Hudaibiyah, the Arab tribes were given the option to join either of the parties, the Muslims or Quraish, with which they desired to enter into treaty alliance. Should any of these tribes suffer aggression, then the party to which it was allied would have the right to retaliate. As a consequence, Banu Bakr joined Quraish, and Khuza'ah joined the Prophet peace be upon him. They thus lived in peace for sometime but ulterior motives stretching back to pre-Islamic period ignited by unabated fire of revenge triggered fresh hostilities. Banu Bakr, without caring a bit for the provisions of the treaty, attacked Banu Khuza'ah in a place called Al-Wateer in Sha'ban, 8 A.H. Quraish helped Banu Bakr with men and arms taking advantage of the dark night. Pressed by their enemies, the tribesmen of Khuza'ah sought the Holy Sanctuary, but here too, their lives were not spared, and, contrary to all accepted traditions, Nawfal, the chief of Banu Bakr, chasing them in the sanctified area - where no blood should be shed - massacred his adversaries.

When the aggrieved party sought justice from their Muslim allies, the Prophet peace be upon him, as their leader, demanded an immediate redress for not only violating the treaty but also slaying men allied to him in the sanctified area. Three demands were made, the acceptance of any one of them was imperative:

• a) to pay blood money for the victims of Khuza'ah,
• b) to terminate their alliance with Banu Bakr; or
• c) to consider the truce to have been nullified.

This behaviour on the part of Quraish was clearly a breach of the treaty of Al-Hudaibiyah and was obviously an act of hostility against the allies of the Muslims, i.e. Banu Khuza'ah. Quraish immediately realized the grave situation and feared the horrible consequences looming on the horizon. They immediately called for an emergency meeting and decided to delegate their chief Abu Sufyan to Madinah for a renewal of the truce. He directly headed for the house of his daughter Umm Habiba (the Prophet's wife). But as he went to sit on the Messenger's carpet, she folded it up. "My daughter," said he, "I hardly knew if you think the carpet is too good for me or that I am too good for the carpet." She replied, "It is the Messenger of Allâh's carpet, and you are an unclean polytheist."

Being disgusted at the curt reply of his daughter, Abu Sufyan stepped out of her room and went to see the Prophet peace be upon him, but the latter was well aware of his tricks and did not hold him any assurance. He then approached Abu Bakr, but the latter too declined to interfere. He contacted 'Umar to intercede but this great Companion made a point-blank refusal. At last he saw 'Ali bin Abi Talib and began begging him in the most humble words, cunningly alluding to the prospects of mastery over all the Arabs if he were to intercede for the renewal of the treaty. 'Ali also briefly regretted his inability to do anything for him. Abu Sufyan turned his steps back to Makkah in a state of bitter disappointment and utter horror. There he submitted a report of his meeting with his daughter, Abu Bakr, 'Umar and 'Ali's reaction and the meaningful silence of the Prophet. The Makkans were dismayed, but did not expect imminent danger.

On the authority of At-Tabari, the Messenger of Allâh peace be upon him asked 'Aishah ÑÖì Çááå ÚäåÇ, his spouse three days prior to receiving news relating to breaching of covenant, to make preparations peculiar to marching out for war. Abu Bakr, meanwhile, came in and asked 'Aishah ÑÖì Çááå ÚäåÇ what the matter was, showing surprise at the preparations being made as it was not, as he said, the usual time for war. She replied that she had no idea. On the morning of the third day 'Amr bin Sâlim Al-Khuza'i arrived in the company of forty horsemen to brief the Prophet peace be upon him on the plight of his people and seeking the Muslims' help for retaliation. People of Madinah then got to know that Quraish had breached the covenant. Budail followed 'Amr, and then Abu Sufyan and the news was unequivocally confirmed.

With view of securing a complete news black-out concerning his military intentions, the Prophet peace be upon him despatched an eight-men platoon under the leadership of Qatadah bin Rab'i in the direction of Edam, a short distance from Madinah, in Ramadan 8 A.H., in order to divert the attention of people and screen off the main target with which he was preoccupied.

There was so much dread and fear everywhere that Hatib, one of the most trusted followers of the Prophet peace be upon him secretly despatched a female messenger with a letter to Makkah containing intimation of the intended attack. The Prophet peace be upon him received news from the heaven of Hatib's action and sent 'Ali and Al-Miqdad with instructions to go after her. They overtook the messenger, and after a long search discovered the letter carefully hidden in her locks. The Prophet peace be upon him summoned Hatib and asked him what had induced him to this act. He replied, "O Messenger of Allâh peace be upon him! I have no affinity of blood with Quraish; there is only a kind of friendly relationship between them and myself. My family is at Makkah and there is no one to look after it or to offer protection to it. My position stands in striking contrast to that of the refugees whose families are secure due to their blood ties with Quraish. I felt that since I am not related to them, I should, for the safety of my children, earn their gratitude by doing good to them. I swear by Allâh that I have not done this act as an apostate, forsaking Islam. I was prompted only by the considerations I have just explained."

'Umar wanted to cut his head off as a hypocrite, but the Prophet peace be upon him accepted his excuse and granted him pardon, then addressed 'Umar saying: "Hatib is one of those who fought in the battle of Badr. How do you know that he is a hypocrite? Allâh is likely to look favourably on those who participated in that battle. Turning then, to Hatib, he said: "Do as you please, for I have forgiven you."

After making full preparation, the Prophet peace be upon him proceeded to Makkah at the head of ten thousand soldiers on the 10th of Ramadan, 8 A.H. He mandated Abu Ruhm Al-Ghifari to dispose the affairs of Madinah during his absence. When they reached Al-Juhfa, Al-'Abbas bin 'Abdul Muttalib and his family came to join the Prophet peace be upon him. At Al-Abwa', the Muslims came across Abu Sufyan bin Al-Harith and 'Abdullah bin Omaiyah, the Prophet's cousins, but, on account of the harm they had inflicted, and their satiric language, on the believers, they were not welcomed. 'Ali addressed Abu Sufyan to go and beseech the Prophet peace be upon him for pardon and confess his ill-behaviour in a manner similar to that of Yusuf's (the Prophet Joseph) brothers:

"They said: 'By Allâh! Indeed Allâh has preferred you above us, and we certainly have been sinners.'" [12:91] Abu Sufyan observed 'Ali's counsel, to which the Prophet quoted Allâh's Words:

"He said: 'No reproach on you this day, may Allâh forgive you, and He is the Most Merciful of those who show mercy!'" [12:92]

Abu Sufyan recited some verses paying a generous tribute to the Prophet peace be upon him and professing Islam as his only religion.

The Muslims then marched on in a state of fasting until they reached a place called Al-Qadeed where water was available. There they broke fast and resumed their movement towards Mar Az-Zahran. The Quraishites were quite unaware of the development of affairs, but the Prophet peace be upon him did not like to take them by surprise. He, therefore, ordered his men to kindle fire on all sides for cooking purposes. The idea behind this was that Quraish should be afforded full opportunity to assess the situation in which they were pitchforked correctly, and should not endanger their lives by leaping blindly in the battlefield. 'Umar bin Al-Khattab was entrusted with the guard duty. In the meanwhile, Abu Sufyan along with Hakim bin Hizam and Budail bin Warqua', two terrible polytheists, went out to reconnoiter. Before they got near the camp, they met 'Abbas, the Prophet's uncle. He apprised Abu Sufyan of the situation and advised him to accept Islam and persuade his people to surrender before Muhammad peace be upon him; otherwise, his head would be struck off.

Under the prevailing compelling circumstances, Abu Sufyan went in the company of 'Abbas seeking the Prophet's peace be upon him audience. The Muslims were furious to see Abu Sufyan and wanted to kill him on the spot. But the two men managed, not without difficulties, to see the Messenger of Allâh peace be upon him who advised that they see him the following day. The Prophet peace be upon him addressed Abu Sufyan saying: "Woe to you! Isn't it time for you to bear witness to the Oneness of Allâh and Prophethood of Muhammad?" Here, the archenemy of Islam began to beseech the Prophet peace be upon him in the most earnest words that testify to the Prophet's generosity and mild temper begging for pardon and forgiveness, and professing wholeheartedly the new faith. On request by 'Abbas, the Prophet peace be upon him, in the context of the general amnesty he proclaimed, gave Abu Sufyan, who had a liking for bragging, a special privilege, saying: "He who takes refuge in Abu Sufyan's house is safe; whosoever confines himself to his house, the inmates thereof shall be in safety, and he who enters the Sacred Mosque is safe."

On the morning of Tuesday, 17th. Ramadan, 8 A.H., the Prophet peace be upon him left Mar Az-Zahran. He ordered Al-'Abbas to detain Abu Sufyan at a commanding gorge that could afford a full view of the Muslim army parading on its way towards Makkah, and hence give him the chance to see the great and powerful soldiers of Allâh. The different tribes successively passed with their banners flown up, until at last the battalion of the Emigrants and Helpers with the Prophet peace be upon him at their head heavily armed marched by. Abu Sufyan began to wonder who those people were, to which Al-'Abbas told him that they were Muhammad peace be upon him and his Companions. Abu Sufyan said that no army however powerful could resist those people and addressing Al-'Abbas, he said: "I swear by Allâh that the sovereignty of your brother's son has become too powerful to withstand." Al-'Abbas answered, "It is rather the power of Prophethood," to which the former agreed.

Sa'd bin 'Ubadah carried the flag of the Helpers. When he passed by Abu Sufyan, he said "Today will witness the great fight, you cannot seek sanctuary at Al-Ka'bah. Today will witness the humiliation of Quraish." Abu Sufyan complained about this to the Prophet peace be upon him who got angry and said "Nay, today Al-Ka'bah will be sanctified, and Quraish honoured," and quickly ordered that Sa'd should be stripped off the flag, and that it should be entrusted to his son Qais, in another version, to Az-Zubair.
