Chapter: Encouragement to pray at night even if it is little
Hadith Number 774
'Abdullah (b. Mas'ud) reported that a mention was made of a man who slept the whole night till morning. He (the Holy Prophet) remarked
That is a man in whose ears (or in whose ear) the devil urinated.
Hadith Number 775
Husain b. 'Ali narrated on the authority of (his father) 'Ali b. Abu Talib that the Messenger of Allah (ﷺ) 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 (ﷺ) 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.
Hadith Number 776
Abu Huraira transmitted it from the Messenger of Allah (ﷺ)
When any one of you goes to sleep, the devil ties three knots at the back of his neck, sealing every knot with:" You have a long night, so sleep." So if one awakes and mentions Allah, a knot will be loosened; if he performs ablution two knots are loosened; and if he prays (all) knots will be loosened, and in the morning he will be active and in good spirits; otherwise we will be in bad spirits and sluggish in the morning.
