'Abdullah bin 'Umar (RA) reported: We waited one night in expectation of the Messenger of Allah ( صلی اللہ علیہ وسلم ) for the last prayer of the night, and he came out to us when a third of the night had passed even after that. We do not know whether he had been occupied with family business or something else. When he came out he said: You are waiting for prayer, for which the followers of no other religion wait, except you. Were it not a burden for my Ummah, I would have led them (in the 'Isha' prayer) at this hour. He then ordered the Mu'adhdhin (to call for prayer) and then stood up for prayer and observed prayer.

'Abdullah bin 'Umar reported that the Messenger of Allah ( صلی اللہ علیہ وسلم ) was one night occupied (in some work) and he delayed it ('Isha' prayer) till we went to sleep in the mosque. We then woke up and again went to sleep and again woke up. The Messenger of Allah ( صلی اللہ علیہ وسلم ) then came to us and said: None among the people of the earth except you waits for prayer in the night.
