Abu Huraira said that when Fatima went to the Prophet and asked him for a servant, he said, “Let me guide you to something which is better than a servant. You should say ‘Glory be to God thirty-three times, ‘Praise be to God" thirty-three times, and ‘God is most great’ thirty-four times at each time of prayer and when you go to bed.”
Narrated ‘Ali said that Fatima went to the Prophet to complain of the effect of the grinding-stone on her hand, as she had heard that he had acquired some slaves, but did not find him, so she mentioned the matter to ‘A'isha. When he came ‘A'isha informed him. ‘Ali said:
He visited us when we had gone to bed, and when we were about to get up he told us to stay where we were. He then came and sat down between her and me, and I felt the coldness of his foot on my belly. He then said, “Let me guide you to something better than what you have asked. When you go to bed, say ‘Glory be to God’ thirty-three times, ‘Praise be to God’ thirty-three times, and ‘God is most great’ thirty-four times. That will be better for you than a servant.”
Abu Huraira said that God’s messenger would say in the morning, "O God, by, Thee we come to the morning, by Thee we come to the evening, by Thee we live, by Thee we die, and to Thee do we come." In the evening he said, “O God, by Thee we come to the evening, by Thee we come to the morning, by Thee we live, by Thee we die, and to Thee are we resurrected.”
Anas told that when God’s messenger went to his bed he said, “Praise be to God who has fed us, given us drink, satisfied us and given us refuge. Many there are who have no one to provide sufficiency for them, or give them refuge.”
