Al-A'raf · 7:150

150. Moses returned to his people from his meeting with His Lord full of anger and sadness upon finding them worshipping the calf. He said: 'What an evil condition you have fallen into after me O people, which leads only to ruin and misery! Were you tired of waiting for the appointed time of your Lord assigned for me – the forty nights – so you started to worship the calf!' Moses threw the Tablets down because of his extreme anger and sadness, and took his brother Aaron by the head and beard and dragged him, because he had been with them and had not been able to stop them from worshipping the calf. Aaron said to his brother Moses: 'O son of my mother, indeed the people considered me to be weak, not respecting me, and they had almost killed me; so do not punish me in a way that would make my enemies rejoice, and do not to include me out of your anger among the people who had done wrong by worshipping other than Allah.'
