Al-Harith b. Muslim at-Tamimi quoted his father as saying that God’s messenger told him secretly to say seven times when he had finished the sunset prayer, before speaking to anyone, “O God, protect me from hell”; for if he said that and died that night, exemption from it would be recorded for him. He also told him to say that when he had prayed the morning prayer, for if he died that day, exemption from it would be recorded for him.
Abu ‘Ayyash reported God's messenger as saying that if anyone says in the morning, “There is no god but God alone who has no partner; to Him belongs the dominion, to Him praise is due, and He is omnipotent,” he will have a reward equivalent to that for setting free a slave from among the descendants of Ishmael, will have ten good deeds recorded for him, will have ten evil deeds deducted from him, will be advanced ten degrees, and will be guarded from the devil till the evening. If he says them in the evening he will have a similar recompense till the morning. Hammad b. Salama said that a man saw God’s messenger in a dream and said, “Messenger of God, Abu ‘Ayyash is relating such and such on your authority,” to which he received the reply, “Abu ‘Ayyash has spoken the truth.”
Ibn ‘Umar said that God’s messenger never failed to use these words evening and morning, “O God, I ask Thee for security in this world and the next; O God, I ask Thee for forgiveness and security in my religion and my worldly affairs, in my family and my property; O God, conceal my faults and keep me safe from the things which I fear; O God, guard me in front of me and behind me, on my right hand and on my left, and from above me; and I seek refuge in Thy greatness from receiving unexpected harm from below me.” Waki‘ said he meant being swallowed up by the earth.
Ibn ‘Abbas reported God’s messenger as saying that if anyone repeats in the morning, "So glory be to God in the evening and in the morning; to Him is the praise in the heavens and the earth; and in the late evening and at noon .. . thus shall you be brought forth," he will get that day what he has missed; and if anyone repeats these words in the evening he will get that night what he has missed.
