A man who forgot the obligatory tawaf

Waki' said: I asked Sufyan: "If a person forgets to perform the obligatory tawaf, and he performs the farewell tawaf (tawaf al-sadr) and then departs?" Sufyan said: The farewell tawaf counts as the obligatory one, and a sacrifice (dam) is due from him for the farewell tawaf.

And al-Hasan bin Salih said: It will not suffice for him; it is as if he did not perform tawaf at all.

And concerning a person performing Qiran who arrives and performs the tawaf for Hajj before the Umrah, he said: The tawaf he performed for Hajj will be made to count for the Umrah, and the tawaf of Hajj remains due from him.

And al-Hasan bin Salih said: It will not suffice for him.

Sufyan said: When (the prostration of) forgetfulness, the talbiyah and the takbir all fall due on a person together, he should begin with the forgetfulness, then the talbiyah, and then say the takbir.
