Aaron had already, before this said to them: "O my people! ye are being tested in this: for verily your Lord is (Allah) Most Gracious; so follow me and obey my command." (90)
Tafsir
After the departure of Moses, Aaron, entrusted with the responsibility of looking after the community, tried to guide his people, but he did not have as much influence over them as Moses did. So they did not desist from their wrongful practice of calf-worship, in spite of Aaron advising them against it. When Aaron’s insistence increased, they expressed their determination to continue. They pointed out that it would be for Moses to take a decision in this matter on his return. Had Aaron acted with sternness, it would have had no effect, because his supporters were few in number. He, therefore, preferred for the time being, to adopt a policy of patience, rather than launch himself on a futile course of action; in the meantime he prayed to God for the reformation of his people.
