Musnad Ahmad Hadith 2558

I stayed with Maimoonah the wife of the Prophet (ﷺ) who was my maternal aunt, on a night when she was not praying. She took a cloth and folded it up, and put a pillow on top of it, then she threw another cloth over it and covered herself with it. She spread out another mat for me and I put my head on the same pillow as her. Then the Prophet (ﷺ) came when he had prayed 'Isha', and he took a cloth and wrapped himself in it, and took off his garment, then he lay down with her under the same blanket. Then at the end of the night, he got up and went to a waterskin that was hanging and shook it. I wanted to get up and pour water for him, but I did not want him to know that I was awake. He did wudoo’, then he went to the bed and put on his two garments and took off the wrapper. Then he went to the mosque, where he stood and prayed. I went to the waterskin and did wudoo', then I came to the mosque and stood on his left, but he moved me and made me stand on his right. He prayed and I prayed, thirteen rak'ahs, then he lay down and I lay down beside him. He put his elbow on my side and his check was next to my cheek until I heard the breathing of one who is asleep. Then Bilal came and said: Prayer, O Messenger of Allah. He went to the mosque and I followed him, and he prayed the two (Sunnah) rak'ahs of Fajr, then Bilal began to recite the iqamah.
