According to Ash-Shafi’i and Ahmad, the time for it is from the midnight of the Day of Nahr, the 10th of Zhul-Hijjah, and its end is indefinite. A male pilgrim is, however, not permitted to have sexual intercourse with his wife until after he completes Tawaf Al-Ifadah. Delaying it beyond the 11th, 12th and 13th of Zhul-Hijjah, does not obligate a person to slaughter an animal, but it is disliked.
The best time for performing this Tawaf is before noon on the Day of Nahr, the 10th of Zhul-Hijjah. According to Abu Hanifah and Malik its time is from the dawn on the Day of Nahr, though concerning its end there is disagreement among scholars.
Abu Hanifah holds that it must be performed during the Days of Nahr, but if a pilgrim delays it beyond these then he must slaughter an animal in atonement 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 Zhul-Hijjah, though doing it earlier (during the Days of Tashriq) is better. Its time is until the end of the month of Zhul-Hijjah, and if it is performed after it. then one must slaughter an animal in atonement. The Hajj of such a person will still be valid, for the whole month of Zhul-Hijjah, according to Malik, is included in the months of Hajj.
