When does a pilgrim become fully lawful (Hall) from the prohibitions of Ihram after performing Tawaf al-Ziyarah?
Chapter on the Description of Hajj
Al-Mughni
Book of Hajj
Primary text
After performing the Sa'i (running between Safa and Marwah) and the Nahr (slaughtering the sacrifice) and Halq (shaving the head) associated with the Day of Sacrifice (Yawm al-Nahr), everything prohibited by Ihram becomes lawful for the pilgrim. Specifically, this Tawaf, when completed according to the sequence detailed by Al-Kharqi, permits intimacy with one's spouse. Ibn Umar reported that the Prophet (peace be upon him) was not lawful from anything prohibited by Ihram until he completed his Hajj, sacrificed his offering on the Day of Sacrifice, circumambulated the House, and then became lawful from everything prohibited.

If the Sa'i was not performed alongside the Tawaf al-Qudum, the pilgrim does not become lawful until the Sa'i is performed, depending on whether Sa'i is considered a pillar (rukn) or a Sunnah. If it is obligatory, he must perform it to become lawful; if it is a Sunnah, there are differing opinions on whether he can become lawful beforehand.
