Muwatta Malik, 737

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to pray in the mosque of Dhu'l-Hulayfa, and then go outside and get on his camel and when his camel had stood up he would begin to do talbiya

Nafe' a rapporté que Abdallah Ibn Omar faisait la prière dans la mosquée de «Zoul-Houlaifa», puis il quittait de façon que, une fois que sa monture fut relevée, il se mettait en état d'ihram»
