The best time to perform Tawaf Al-Ifadah is before noon on the day of sacrifice, though there is a disagreement among scholars concerning its end.
Sheikh Sayyed Sabiq states in his well-known book FiqhAs-Sunnah: According to Ash-Shafi`i and Ahmad, Tawaf Al-Ifadah can be performed from midnight of the day of sacrifice, the 10th of Dhul-Hijjah, and its end is indefinite. A male pilgrim is not permitted to have sexual intercourse with his wife until after he has completed Tawaf Al-Ifadah. Delaying it beyond the 11th, 12th and 13th of Dhul-Hijjah does not obligate a person to slaughter an animal, but it is disliked.
The best time to perform this Tawaf is before noon on the day of sacrifice. According to Abu Hanifah and Malik its time is from dawn on the day of sacrifice, though there is a disagreement among scholars concerning its end. Abu Hanifah says that it must be performed during the days of sacrifice, and if a pilgrim delays it beyond these days he must slaughter an animal to atone for it. Malik, on the other hand, is of the view that there is no harm in delaying this rite until after the 13th of Dhul-Hijjah, though doing it earlier (during the days of Tashriq) is better. Its time is until the end of the month of Dhul-Hijjah, and if it is performed after that time, then one must slaughter an animal in atonement. The Hajj of such a person will still be valid because according to Malik, the whole month is included in the months of Hajj.
