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 regret overcame them and they saw that they had gone astray, they said, "If our Lord does not have mercy upon us and forgive us, we will surely be among the losers." 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 Said [Moses]: "O my Sustainer! Grant Thou forgiveness unto me and my brother, and admit us unto Thy grace: for Thou art the most merciful of the merciful!" 151
