Allah the Exalted and Great revealed (a verse) regarding those who were killed at Bi'r Ma'una, and we recited it, till it was abrogated later on (and the verse was like this):, convey to it our people the tidings that we have met our Lord, and He was pleased with us and we were pleased with Him".
دَعَا رَسُولُ اللَّهِ ﷺ عَلَى الَّذِينَ قَتَلُوا أَصْحَابَ بِئْرِ مَعُونَةَ ثَلاَثِينَ صَبَاحًا يَدْعُو عَلَى رِعْلٍ وَذَكْوَانَ وَلِحْيَانَ وَعُصَيَّةَ عَصَتِ اللَّهَ وَرَسُولَهُ قَالَ أَنَسٌ أَنْزَلَ اللَّهُ ﷻ فِي الَّذِينَ قُتِلُوا بِبِئْرِ مَعُونَةَ قُرْآنًا قَرَأْنَاهُ حَتَّى نُسِخَ بَعْدُ أَنْ بَلِّغُوا قَوْمَنَا أَنْ قَدْ لَقِينَا رَبَّنَا فَرَضِيَ عَنَّا وَرَضِينَا عَنْهُ
