Al-Bara b. ‘Azib said :
The Messenger of Allah ﷺ said to me: When you go to your bed, perform ablution like the ablution for prayer, and then lie on your right side and say: O Allah I have handed over my face to thee, entrusted my affairs to thee, and committed my back to thee out of desire for and fear to thee. There is no refuge and no place of safety from thee except by having recource to thee. I believe in Thy Book which Thou hast sent down and in Thy prophet whom thou hast sent down. He said : If you die (that night), you would die in the true religion, and utter these words in the last of that you utter (other prayers). Al-Bara said : I said: I memorise them, and then I repeated, saying “and in Thy Apostle whom Thou hast sent”. He said : No, say : “and in Thy Prophet whom Thou hast sent.
