Sahih al-Bukhari
Hajj (Pilgrimage)
Chapter: The visit (of the Ka'bah) to perform (Tawaf-al-Ifada) on the Day of Nahr
Narrated `Aisha:
We performed Hajj with the Prophet (ﷺ) and performed Tawaf-al-ifada on the Day of Nahr (slaughtering). Safiya got her menses and the Prophets desired from her what a husband desires from his wife. I said to him, "O Allah's Messenger (ﷺ)! She is having her menses." He said, "Is she going to detain us?" We informed him that she had performed Tawaf-al-Ifada on the Day of Nahr. He said, "(Then you can) depart."
