110 Hadith Qudsi, Chapter: 110 Ahadith Qudsi (Sacred Hadith)

I heard Allah's Messenger (PBUH) saying: One of my followers gets up at night pushing himself to perform ablution (for prayer). On him there are several knots of the Satan. When he washes his hands, a knot loosens. When he washes his face, another knot loosens. When he passes his wet hands over his head, yet another knot loosens. When he washes his legs, the last knot loosens. Then Allah (SWT) says to those beyond the eyes (angels): Look at this slave of Mine who cures/his inner-self and asks Me forgiveness. So, what he asks is given to him. (This Hadith is sound and reported by Ibn Hibban and Ahmad in his Musnad).
