After all those Messengers (sent to the past generations that are now all extinct,) We sent Moses and his brother Aaron as Messengers with Our clear signs (miracles to support them) and a manifest authority (from Us)
Then We sent Moosa (Moses) and his brother Haroon (Aaron), with Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) and manifest authority
Then We sent Our messengers one after another. Whenever its messenger came to a community, it denied him, so We made some of them to follow others and We made them stories, so away with the people who do not believe.
