And Musa's people made of their ornaments a calf after him, a (mere) body, which gave a mooing sound. What! could they not see that it did not speak to them nor guide them in the way? They took it (for worship) and they were unjust. 148 And when they regretted and saw that they had gone astray, they (repented and) said: "If our Lord have not mercy upon us and forgive us, we shall certainly be of the losers." 149 When Moses returned to his people in anger and great sorrow, he said, "What an awful sin you have committed in my absence. Did you want to hasten your Lord's command?" He threw down the Tablets and seized his brother by the head, pulling him towards himself. Aaron said, "Son of my mother, the people oppressed me and almost killed me. Do not give my enemies cause to gloat over me. Do not number me among the wrongdoers." 150 He said, 'O my Lord, forgive me and my brother and enter us into Thy mercy; Thou art the most merciful of the merciful.' 151
