Book of Hajj

1. Hajj is one of the pillars of Islam and is a fardh obligation according to both Qur'an and sahih Hadith.
2. It and 'Umrah are obligatory once in a lifetime (difference of opinion about 'Umrah)
3. The five conditions for its obligation are:
   1. Islam
   2. Sound mind
   3. Adulthood (defined as puberty in Islam)
   4. Freedom
   5. Ability
4. They are valid if performed by a child, but do not fulfill the lifetime requirement.
5. If the blocking condition is removed in time to stand at Arafat, then the Hajj fulfills the lifetime obligation.
6. LIkewise for 'Umrah as long as it is before the Tawwaaf.
7. Ability means one who possesses appropriate provisions and means of transportation. (Or it is more general than that.)
8. Whoever possesses the mean is required to begin immediately striving to get to the Hajj and it is a sin to postpone it with no valid excuse.
9. If physically unable, one should seek another man or woman to do it on his behalf. (According to some, this is only for parents.)
10. If someone dies who was obligated to make Hajj without making it, the proxy should be provided for from his estate.
11. No one who has not made their own Hajj can make it for another.
12. In addition to the five conditions in the case of a woman it is also a condition that she find a husband or other mahram to accompany her.
13. Also, part of her "ability" is that she can suffice his expenses, if necessary.
14. If she makes Hajj without a mahram, she commits a sin, but the Hajj is valid.
15. If the mahram dies on the way, she can continue with her Hajj.
