Sunan an-Nasa'i 1128

Yahya ibn ‘Uthman reported to us; he said: Ibn Humayr informed us; he said: Shu‘ayb ibn Abi Hamzah narrated to us, from Muhammad ibn al-Munkadir—and he mentioned another narrator before him—from ‘Abd al-Rahman ibn Hurmuz al-A‘raj, from Muhammad ibn Maslamah, that the Messenger of Allah (ﷺ), when he got up at night to perform voluntary prayer, would say upon prostrating: “O Allah, to You I have prostrated, in You I have believed, and to You I have submitted. O Allah, You are my Lord. My face has prostrated to the One who created and fashioned it, and made its hearing and sight. Blessed is Allah, the Best of creators.”
