The State of Consecration (ihrām) for the Pilgrimage
As aforementioned, there are 13 obligations of the pilgrimage, which will be now outlined in detail.
The first obligation:
The best time for entering the state of consecration is the time of the noon prayer on the day of Tarwiyah. That is the eighth day of the month of Dhu-l-Hiğğah. It is permissible to assume the state of ihrām prior to that, e.g. for the elderly or the ill who fear the crowding of the masses and are therefore leaving Mecca before the other pilgrims. If necessary, the pilgrim can enter the state of consecration for the Hajj and then depart from Mecca directly after completing the ´Umratu-t-Tamattu´.
A woman who is expecting her period is allowed to assume the state of consecration early in order to perform the ṯawāf and the ṯawāf prayer in advance of it.
#358: Just as one is not permitted to assume the state of ihrām for the Hajj before performing the taqsīr for the ´Umratu-t-Tamattu´, one is also not permitted to enter the state of consecration for the ´Umratu-l-Mufradah before terminating the state of ihrām for the Hajj.
#359: If the pilgrim is able to reach Arafat early enough to stay there during the preferable time, they are not allowed to delay assuming the state of ihrām so long that they can no longer arrive in time.
#360: The rules governing the procedure, obligations and prohibitions during the state of ihrām are the same for both the Hajj and the ´Umrah. The only difference is in the intention, which has to be set for the ´Umrah and for the Hajj respectively.
#361: As aforementioned, it is an obligation to enter the state of ihrām for the Hajj in Mecca. The best place for that purpose is the Holy Mosque, and it is recommended that one begin to do so after praying two raka´as at the Maqam Ibrahim or at the Hijr Ismail.
#362: If a pilgrim does not enter the state of consecration due to ignorance or forgetfulness and leaves Mecca without being in the state of ihrām and then they remember or are instructed about it, they have to return to Mecca in order to enter the state of ihrām there even if they are already in Arafat. If this is not possible due to lack of time or for other reasons, they have to assume the state of ihrām at their present location. The same applies if they do not remember or learn about it until after their stay at Arafat even if they could return to Mecca to enter the state of consecration.
However, if the pilgrim does not become aware of or learn about it before having completed the pilgrimage, their Hajj is still valid.
#363: If a pilgrim knowingly and deliberately neglects to enter the state of consecration and therefore is unable to stay at Arafat during the recommended time, their Hajj is invalid.
If they succeed in assuming the state of consecration and the obligatory wuqūf in time, their Hajj is not invalid, although this is an offense.
#364: To be on the safe side, one should not perform an optional ṯawāf after entering the state of ihrām for the Hajj and before proceeding towards Arafat. If it is done nonetheless, as a precaution, the talbiyyah should be renewed after the ṯawāf.
