And the people of Moses made, after [his departure], from their ornaments a calf - an image having a lowing sound. Did they not see that it could neither speak to them nor guide them to a way? They took it [for worship], and they were wrongdoers. 148 And when they repented and saw that they had strayed, they said: if our Lord have not mercy on us and forgive us not, we shall surely be of the losers. 149 And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people. 150 He said: My Lord! forgive me and my brother and cause us to enter into Thy mercy, and Thou art the most Merciful of the merciful ones. 151
