Abu Huraira told that when the Prophet went to his bed he used to say, “O God, Lord of the heavens, Lord of the earth, Lord of everything, who splittest the grain and the kernel, who hast sent down the Torah, the Injil and the Qur’an, I seek refuge in Thee from the evil of every evil agent whose forelock Thou seizest. Thou art the First and there is nothing before Thee; Thou art the Last and there is nothing after Thee; Thou art the Outward and there is nothing above Thee; Thou art the Inward and there is nothing below Thee. Pay the debt for me and grant me riches instead of poverty.”
Abu Dawud, Tirmidhi and Ibn Majah transmitted it. Muslim also transmitted it with a slight difference.
‘Abdallah b. Ghannam reported God’s messenger as saying, that if anyone says in the morning, "O God, whatever favour has come to me or to any of Thy creatures in the morning, it comes from Thee alone who hast no partner, to whom be praise and thanksgiving," he will have expressed full thanksgiving for the day; and if anyone says the same in the evening he will have expressed full thanksgiving for the night.
Abul Azhar al-Aimari told that when God’s messenger went to his bed at night he said, “In the name of God. I have laid down my side for God. O God, forgive me my sin, drive away my devil, free me from my responsibility, and place me in the highest assembly.”
‘Abdallah b. ‘Amr b. al-‘As reported God’s messenger as saying there are two characteristics which will not be retained by any Muslim without his entering paradise. While they are easy, those who act upon them are few. One should say ‘Glory be to God’ ten times after every prayer, ‘Praise be to God’ ten times and ‘God is most great’ ten times. (He said he had seen God’s messenger counting them on his hand, and saying, “That is a hundred and fifty on the tongue, but one thousand five hundred in the scale”). When he goes to his bed he should say ‘Glory be to God,’ ‘God is most Great’ and ‘Praise be to God’ a hundred times, for that is a hundred on the tongue, but a thousand in the scale. He asked them which of them could commit two thousand five hundred sins in a day and a night.* He was asked how they could not retain these characteristics, and told them that the devil comes to a man while he is engaged in prayer, calling such and such and such and such to his memory until he turns away and perhaps may not do it. He also comes to him on his bed and keeps on making him sleep till he falls asleep.
*The thousand plus the preceding fifteen hundred make two thousand five hundred good deeds with which the man who observes the two characteristics mentioned is credited, and as one could hardly commit as many sins in a day and a night there is a balance in his favour.
Tirmidhi, Abu Dawud and Nasa’i transmitted it. In Abu Dawud's version he said, “Two qualities or two characteristics will not be adhered to by a Muslim ...” And also in his version after saying “One thousand five hundred in the scale” he said, “When he goes to his bed he should say ‘God is most great’ thirty-four times, ‘Praise be to God’ thirty-three times and ‘Glory be to God’ thirty-three times.” In most texts of al-Masabih it is given on the authority of ‘Abdallah b. ‘Umar.
