Riyad us Saliheen: Hadith 1462

Whenever the Prophet (ﷺ) went to his bed, he would say: "Al-hamdu lillah-illadhi at'amana wa saqana, wa kafana wa awana, fakam mimman la kafiya lahu wa la mu'wiya (Praise is due to Allah Who has fed us, provided us drink, satisfied us and gave us protection. Many are those who have no one to provide for them, or give them shelter)."

[Muslim].
