مختصر صحيح مسلم
Mukhtasar Sahih Muslim
Book of Remembrance
What to say when sleeping or lying down.
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) would go to his bed, he would say: "All praise is due to Allah who has fed us, given us drink, sufficed us, and provided us with shelter. How many are there who have no one to suffice them and no one to provide them with shelter."
