Musnad Ahmad Hadith 3170

I stayed overnight with my maternal aunt Maimoonah. The Messenger of Allah (ﷺ) got up in the night, relieved himself and washed his face and hands. Then he got up, went to the waterskin, undid its straps, and did a wudoo’ that was somewhere between the most perfect and the most light; he did not use a great deal of water but he did a proper wudoo’. Then he stood and prayed, and I got up and hid myself, not wanting him to think that I was watching him, and I did wudoo’. He stood and started praying, and I stood on his left, but he took me by the ear and brought me round to his right. The prayer of the Messenger of Allah (ﷺ) at night reached thirteen rak'ahs. Then he lay down and slept until he was breathing deeply, for when he slept he would breathe deeply. Then Bilal came to him and called him for prayer, and he got up and prayed, and did not do wudoo’. In his du’a’ he said: "O Allah, put in my heart light, in my seeing light, in my hearing light, to my right light, to my left light, above me light, below me light, in front of me light, behind me light, give me abundant light." Kuraib said: There are seven more phrases that I was caused to forget. I met one of the sons of al-'Abbas and he told them to me. He mentioned: my sinews, my flesh my blood, my hair and my skin, and he mentioned two others.
