‘Amr b. Shu'aib, on his father’s authority, said that his grandfather reported God's messenger as saying, “If anyone glorifies God a hundred times in the morning and a hundred times in the evening, he will be like one who makes the Pilgrimage a hundred times; if anyone praises God a hundred times in the morning and a hundred times in the evening, he will be like one who provides a hundred horses, as mounts in God’s path; if anyone declares that God is the only God a hundred times in the morning and a hundred times in the evening, he will be like one who frees a hundred of the descendants of Ishmael who are slaves; if anyone declares God’s greatness a hundred times in the morning and a hundred times in the evening, no one will bring more than he does that day, except one who says the same as he did or more.” Tirmidhi transmitted it, saying this is a hasan gharib tradition.
