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 feared the consequences thereof and saw that they had gone astray, they said: Unless our Lord have mercy on us and forgive us, we verily are of the lost. 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: 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
