[The angels said], "O Abraham, give up this [plea]. Indeed, the command of your Lord has come, and indeed, there will reach them a punishment that cannot be repelled."
The angels told Abraham to leave off debating about the people of Lot: the command of his Lord had come that they would receive the punishment He had decreed for them, and there was a great punishment coming to the people of Lot, which no debate or prayer could turn back.
