‘Amir b. Sa'd quoted his father as saying that he used to see God’s Messenger giving the salutation* to his right and his left, so that he could see the whiteness of his cheek.
Abu Bakr as-Siddiq said that he asked God’s Messenger to teach him a supplication to use in his prayer, and he told him to say, “O God, I have greatly wronged myself, and Thou alone canst forgive sins, so grant me forgiveness from Thee and show mercy to me. Thou art the forgiving and the merciful One.”
