I ask You for the good of this night and the good of what comes after it, and I seek refuge in You from the evil of this night and the evil of what comes after it, and I seek refuge in You from laziness and the misfortune of old age, and I seek refuge in You from the punishment of the Fire and the punishment of the grave. And when he reached the morning, he would say the same: "We have entered the morning, and the dominion belongs to Allah, and praise belongs to Allah." (1)

This is a good and authentic hadith. Shu'bah narrated it with this chain of transmission from Ibn Mas'ud, but he did not raise it to the Prophet (2).

3688 - 'Ali ibn Hujr narrated to us, he said: 'Abdullah ibn Ja'far narrated to us, he said: Suhayl ibn Abi Salih informed us, from his father, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, used to teach his companions, saying: "When one of you enters the morning, let him say: 'O Allah, by You we have entered the morning, and by You we have entered the evening, and by You we live, and by You we die, and to You is the final return.' And when he enters the evening, let him say: 'O Allah, by You we have entered the evening, and by You we have entered the morning, and by You we live, and by You we die, and to You is the resurrection.'" (3)
