The limits of intercession (shafāʿah)

يَـٰٓإِبْرَٰهِيمُ أَعْرِضْ عَنْ هَـٰذَآ ۖ إِنَّهُۥ قَدْ جَآءَ أَمْرُ رَبِّكَ ۖ وَإِنَّهُمْ ءَاتِيهِمْ عَذَابٌ غَيْرُ مَرْدُودٍ

[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."
