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 When they repented, and saw that they had erred, they said: "If our Lord have not mercy upon us and forgive us, we shall indeed be of those who perish." 149 When Moses returned to his people, indignant and grieved, he said: "How wickedly you behaved in my absence. Why must you hasten the decree of your Lord?" And he cast aside the tablets, and pulled his brother by the hair. "O son of my mother," said (Aaron), "these people took advantage of my weakness and almost killed me. Do not let my enemies rejoice at my plight, and do not put me down among transgressors." 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
