Sahih Muslim
The Book of Prayers (Kitab Al-Salat)
Book Number: 004 / Hadith Number: 1037
'Urwa b. Zubair reported: 'A'isha asked: What disrupts the prayer? We said: The woman and the ass. Upon this she remarked: Is the woman an ugly animal? I lay in front of the Messenger of Allah (may peace be upon him) like the bier of a corpse and he said prayer.
