Good Manners and Form (Al-Adab)
Bukhari :: Book 8 :: Volume 73 :: Hadith 178
Narrated 'Aisha:
The Prophet intended to return home after the performance of the Hajj, and he saw Safiya standing at the entrance of her tent, depressed and sad because she got her menses. The Prophet said, "Aqra Halqa! --An expression used in the Quraish dialect--"You will detain us." The Prophet then asked (her), "Did you perform the Tawaf Al-Ifada on the Day of Sacrifice (10th of Dhul-Hijja)?" She said, "Yes." The Prophet said, "Then you can leave (with us)."
