The Heights - 7:150
"When Moses returned to his people, angry and disappointed, they said, "What evil deeds you have done after me! Have you not been able to endure the command of your Lord?"He threw down the plates, grabbed his brother´s head and pulled him towards him: "Son of my mother,"he said, "these people have taken advantage of my weakness, and they almost killed me. Do not make the enemy laugh by coming upon me, and do not associate me with this cruel people."
Why did the people of Moses serve the calf?
The Cow/2:93
"Remember when We raised Mount Tur over you and took a promise from you: "Hold fast to what I command you and listen."But they said: "We listened and disobeyed". Because of their disbelief, their hearts were deceived by the calf. Say: "If you have believed, how badly your faith is guiding you!"
The Table Spread/5:71
They thought that they would not be tested, and they became blind and deaf. Then Allah accepted their inclination, but most of them again became blind and deaf. Allah sees what they do.
