Abu Umamah Al-Bahili said:“I heard the Messenger of Allah (ﷺ) saying: “Whoever goes to his bed while in a state of purity and remembering Allah, until slumber overtakes him, he shall not get up at any hour of the night and ask Allah for something from the good of the world and the Hereafter except that Allah shall grant it to him.’”
