'Abdullah bin 'Umar reported: I heard the Messenger of Allah (ﷺ) 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 (ﷺ) 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.

Abu Salama is reported to have said. I came to 'A'isha. I said: O mother, inform me about the prayer of the Messenger of Allah (ﷺ) . She said: His (night prayer) in Ramadan and (during other months) was thirteen rak'ahs at night including two rak'ahs of Fajr.

Abu Salama reported: I asked 'A'isha (Allah be pleased with her) about the fasting of the Messenger of Allah (ﷺ) . She said: He used to observe fast (at times so continuously) that we said: He has fasted (never to break), and he did not observe fast till we said: He has given up perhaps never to fast, and I never saw him observing (voluntary fasts) more in any other month than that of Sha'ban. (lt appeared as if) he observed fast throughout the whole of Sha'ban except a few (days).
