And Abu Bakr ibn Abi Shaybah narrated to us, Waki' narrated to us, Sufyan narrated to us, from Abdullah ibn Abi Labid, from Abu Salamah ibn Abd al-Rahman, from Ibn Umar, who said: The Messenger of Allah, peace and blessings be upon him, said: "Do not let the Bedouins overcome you regarding the name of your prayer, the Isha. For it is called al-Isha in the Book of Allah, and it is delayed until the time when the milk of the camels becomes dark."
