(26) باب الدُّعَاءِ فِي صَلاَةِ اللَّيْلِ وَقِيَامِهِ
Ibn `Abbas reported that when the Messenger of Allah (ﷺ) got up during the night to pray, he used to say:
O Allah, to Thee be the praise Thou art the light of the heavens and the earth. To Thee be the praise; Thou art the Supporter of the heavens and the earth. To Thee be the praise; Thou art the Lord of the heavens and the earth and whatever is therein. Thou art the Truth; Thy promise is True, the meeting with Thee is True. Paradise is true, Hell is true, the Hour is true. O Allah, I submit to Thee; affirm my faith in Thee; repose my trust in Thee, and I return to Thee for repentance; by Thy help I have disputed; and to Thee I have come for decision, so forgive me my earlier and later sins, the sins that I committed in secret and openly. Thou art my God. There is no god but Thee.
