Husain b. 'Ali narrated on the authority of (his father) 'Ali b. Abu Talib that the Messenger of Allah ( صلی اللہ علیہ وسلم ) came one night to see him ('Ali) and Fatimah (the daughter of the Holy Prophet) and said:
Don't you observe (Tahajjud) prayer? I ('Ali) said: Messenger of Allah, verily our souls are in the hands of Allah and when He wants to awaken us, He awakens us. The Messenger of Allah ( صلی اللہ علیہ وسلم ) went back when I said this to him. He was striking his hand on his thigh while returning, and I heard him say: Verily the man disputes with many things.
