Yahya related to me from Malik from one of the Ansar that the Messenger of Allah, may Allah bless him and grant him peace, forbade defecating or urinating while facing the qibla.
Muwatta Malik Book 14, Hadith 2
← Previous Hadith Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha that Rafiibn Ishaq, a mawla of the family of ash-Shifa who was known as the mawla of Abu Talha, heard Abu Ayyub al-Ansari, one of the companions of the Messenger of Allah, may Allah bless him and grant him peace, say, while he was in Egypt, "By Allah! I don't know how to deal with these lavatories." The Messenger of Allah, may Allah bless him and grant him peace, said, "When you go to defecate or urinate, do not expose your genitals towards the qibla, and do not put your back to it."

Muwatta Malik Book 14, Hadith 1 Next Hadith → Yahya related to me from Malik from Yahya ibn Said from Muhammad ibn Yahya ibn Habban from his paternal uncle, Wasi ibn Habban, that Abdullah ibn Umar said, "People say, 'When you sit to relieve yourself, do not face the qibla or the Bayt al-Maqdis.' " Abdullah continued, "I went upon top of a house of ours and saw the Messenger of Allah, may Allah bless him and grant him peace, (squatting) on two unfired bricks facing the Bayt al-Maqdis, relieving himself." Ibn Umar added, "Perhaps you are one of those who pray folded on their haunches." Wasi replied, "I don't know, by Allah!"
