It was narrated that Ibn ‘Abbas said: “I stayed overnight with my maternal aunt Maimunah bint Al-Harith, and the Messenger of Allah صلی اللہ علیہ وآلہ وسلم stayed overnight with her. I saw him get up to relieve himself, and he went to the waterskin and undid its string, then he performed Wudu’ that was moderate (in the amount of water used). Then he went to his bed and slept. Then he got up again and went to the waterskin and undid its string, and performed Wug again, like the first time. Then he stood and prayed, and when he prostrated he said: (Allah, place light in my heart, and place light in my hearing, and place light in my seeing, and place light beneath me, and place light above me, and light on my right, and light on my left, and place light in front of me, and place light behind me, and make the light greater for me.’) Then he slept until he started to snore, then Bilal came and woke him up for the prayer.” (Sahih)
