The Prophet said: “When one of you lies down on his right side, then says: ‘O Allah, I have submitted myself to You, and I have turned my face to You, and I lay myself down relying upon You, and I have entrusted my affair to You, there is no refuge minka illā ilaik, ūminu bikitābika wa birusulika)’ – then if he dies that night, he shall enter Paradise.”
Jami` at-Tirmidhi Book 48, Hadith 26
← Previous Hadith The Prophet (ﷺ) said to him: “Should I not teach you some words to say when you go to your bed, so if you died, you will die upon the Fitrah, and if you reach the morning, you will reach it in good? You say: ‘O Allah, verily, I submit myself to You, and I turn my face to You, and I entrust my affair to You, hoping in You and fearing in You. And I lay myself down depending upon You, there is no refuge minka illā ilaik. Āmantu bikitābikal-ladhī anzalta wa binabiyyikal-ladhī arsalt).’” Al-Bara' said: “So I said: ‘And in Your Messenger whom you have sent.’” He said: “So he (ﷺ) struck his hand upon my chest, then said: “And in Your Prophet whom You have sent. (Wa binabiyyikal-ladhī arsalt).”

Jami` at-Tirmidhi Book 48, Hadith 25 Next Hadith → when he went to his bed, the Messenger of Allah (ﷺ) used to say: “All praise is due to Allah, who has fed us and given us to drink, and has sufficed and granted us refuge, and how many are they who have none to suffice them and none to grant them refuge (Al-ḥamdulillāhi alladhi aṭ`amanā wa saqānā wa kafānā wa āwānā, wakam mimman lā kāfiya lahu wa lā mu'wiy).”
