'Abdullah bin 'Umar reported: I heard the Messenger of Allah ( صلی اللہ علیہ وسلم ) as saying: Let the bedouin not gain upper hand over you in regard to the name of your prayer. See the night prayer should be called 'Isha' and the bedouins call it Atama (because) they milk their camels late.

Ibn 'Umar said: The Messenger of Allah ( صلی اللہ علیہ وسلم ) said: Let the bedouin not gain upper hand over you in regard to the name of your prayer, i. e. night prayer, for it is mentioned 'Isha' in the Book of Allah (i. e. the Qur'an). (The bedouin call it 'Atama because) they make delay in milling their she-camels.
