Sahih Muslim 771a — Night Prayer Dua and Devotion

'Ali bin Abi Talib Narrated from:

When the Messenger of Allah (ﷺ) got up at night for prayer he would say: I turn my face in complete devotion to One Who is the Originator of the heaven and the earth and I am not of the polytheists. Verily my prayer, my sacrifice, my living and my dying are for Allah, the Lord of the worlds; There is no partner with Him and this is what I have been commanded (to profess and believe) and I am of the believers.O Allah, Thou art the King, there is no god but Thee, Thou art my Lord, and I am Thy bondman. I wronged myself and make a confession of my Sin. Forgive all my sins, for no one forgives the sins but Thee, and guide me in the best of conduct for none but Thee guideth anyone (in) good conduct. Remove sins from me, for none else but Thou can remove sins from me.Here I am at Thy service, and Grace is to Thee and the whole of good is in Thine hand, and one cannot get nearness to Thee through evil. My (power as well as existence) is due to Thee (Thine grace) and I turn to Thee (for supplication). Thou art blessed and Thou art exalted.I seek forgiveness from Thee and turn to Thee in repentance: and when he would bow, he would say: O Allah, it is for Thee that I bowed. I affirm my faith in Thee and I submit to Thee, and submit humbly before Thee my hearing, my eyesight, my marrow, my bone, my sinew; and when he would raise his head, he would say: O Allah, our Lord, praise is due to Thee, (the praise) with which is filled the heavens and the earth, and with which is filled that (space) which exists between them, and filled with anything that Thou desireth afterward.And when he prostrated himself, he (the Holy Prophet) would say: O Allah, it is to Thee that I prostrate myself and it is in Thee that I affirm my faith, and I submit to Thee. My face is submitted before One Who created it, and shaped it, and opened his faculties of hearing and seeing. Blessed is Allah, the best of Creators; and he would then say between Tashahhud and the pronouncing of salutation: Forgive me of the earlier and later open and secret (sins) and that where I made transgression and that Thou knowest better than I. Thou art the First and the Last. There is no god, but Thee.
