Q 20:90

وَلَقَدْ قَالَ لَهُمْ هَـٰرُونُ مِن قَبْلُ يَـٰقَوْمِ إِنَّمَا فُتِنتُم بِهِۦ ۖ وَإِنَّ رَبَّكُمُ ٱلرَّحْمَـٰنُ فَٱتَّبِعُونِى وَأَطِيعُوٓا۟ أَمْرِى

Translations

And Aaron had already told them before [the return of Moses], "O my people, you are only being tested by it, and indeed, your Lord is the Most Merciful, so follow me and obey my order."

Sahih International · EN

Certes, Aaron leur avait bien dit auparavant: «O mon peuple, vous êtes tombés dans la tentation (à cause du veau). Or, c'est le Tout Miséricordieux qui est vraiment votre Seigneur. Suivez-moi donc et obéissez à mon commandement».

Tafsir

Aaron had said to them before Moses returned to them: “The making of the calf from gold and its mooing are only to test you, to distinguish the believer from the disbeliever. And your Lord, O people, is Allah, so follow me by worshipping Him alone and obey my command to leave worshipping others besides Him”.

Read Ibn Kathir (Ibn Kathir (abridged, English))

And Harun indeed had said to them beforehand: "O my people! You are being tried in this, and verily, your Lord is (Allah) the Most Gracious, so follow me and obey my order. (90)They said: "We will not stop worshipping it, until Musa returns to us. (91) Harun prohibits them from worship of the Calf and the Persistence of the Children of Israel in doing so Allah, the Exalted, informs of Harun's attempt to prohibit them from worshipping the calf and his telling them that this was only a test for them. He told them that their Lord was the Most Beneficent, Who created everything and decreed for everything its just measure. He is the Owner of the Mighty Throne, the One Who does whatever He wants. فَاتَّبِعُونِي وَأَطِيعُوا أَمْرِي (so follow me and obey my order.) Meaning, "Follow me in that which I am commanding you with and leave that which I forbid you from." قَالُوا لَن نَّبْرَحَ عَلَيْهِ عَاكِفِينَ حَتَّىٰ يَرْجِعَ إِلَيْنَا مُوسَىٰ (They said: "We will not stop worshipping it, until Musa returns to us.") meaning, "We will not cease in our worship of this calf until we hear what Musa has to say about it." So they opposed Harun in this matter and they fought against him, nearly killing him.
