It is narrated from Sayyiduna Ali (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) performed prostration, he used to recite this supplication: "O Allah! I have prostrated for You, and I have believed in You, and I have submitted to You. My face has prostrated to the One Who created it, and fashioned it, and gave it the best form, and opened its hearing and sight. So blessed is Allah, the Best of creators." (O Allah! I have prostrated only for You, believed in You, submitted to You; my face has prostrated to the One Who created it, shaped it, made it beautiful, and opened its ears and eyes. Allah is very blessed, the Best of creators.)

Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) narrates the Tahajjud prayer of the Messenger of Allah (peace and blessings be upon him): Then the Prophet (peace and blessings be upon him) went out for prayer and prayed, and during the prayer or in prostration he began to supplicate: O Allah! Place light in my heart, and light in my hearing, and light in my sight, and light on my right, and light on my left, and light in front of me, and light behind me, and light above me, and light beneath me, and make me light. Shu’bah says: Or the last phrase is like this: Make for me light. (O Allah! Place light in my heart, light in my ears, light in my sight, light on my right, light on my left, light in front of me, light behind me, light above me, and light beneath me, and make me light.)

Sayyidah Aisha (may Allah be pleased with her) narrates that she found the Prophet Muhammad (peace and blessings be upon him) missing from the bed, so she searched for him with her hand. When her hand touched him, she realized that the Prophet (peace and blessings be upon him) was in the state of prostration and was supplicating: "O my Lord! Grant my soul its piety, purify it, You are the best to purify it, You are its Guardian and Master."

It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: One night I found the Noble Prophet (peace and blessings be upon him) missing, and I thought that he had gone to another wife. So I searched and looked for the Prophet (peace and blessings be upon him). But when I returned, I saw that the Prophet (peace and blessings be upon him) was in the state of bowing or prostration, reciting this supplication: "Subhanaka wa bihamdika la ilaha illa anta" (Glory be to You and with Your praise, there is no deity except You). And in another narration: He was reciting this supplication in prostration: "Rabbi ighfir li ma asrartu wa ma a'lantu" (O my Lord! Forgive me my hidden and open sins). Seeing this, I said: May my parents be sacrificed for you, indeed I was thinking of something else, and you were engaged in something else.

Sayyiduna Abu Hurairah (may Allah be pleased with him) says: The servant is closest to his Lord while in the state of prostration, so make abundant supplication in it.
