﴿ وَلَقَدْ ءَاتَيْنَا مُوسَى ٱلْكِتَٰبَ وَجَعَلْنَا مَعَهُۥٓ أَخَاهُ هَٰرُونَ وَزِيرًۭا ﴾

“AND, INDEED, [long before Muhammad] We vouchsafed revelation unto Moses, and appointed his brother Aaron to help him to bear his burden;”

And verily We gave Moses the Scripture the Torah and made Aaron his brother go with him as a minister an assistant.
