1 hadith
Hadith 1977
Sayyiduna Ali (may Allah be pleased with him) narrates: Whenever the Prophet Muhammad (peace and blessings be upon him) went into prostration, he used to recite: "O Allah! I have prostrated for You, I have believed in You, and I have submitted to You. My face has prostrated before the One Who created it, fashioned it, and gave it a beautiful form, Who granted it hearing and sight. So blessed is Allah, the Best of creators."
