باب آخِرِ آيَةٍ أُنْزِلَتْ آيَةُ الْكَلاَلَةِ ‏‏
Sahih Muslim 1618 d

Aba Ishaq reported this hadith on the authority of al-Bara' (Allah be pleased with him) with a slight variation of words, viz. the last sura that was revealed complete.

حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا يَحْيَى، - يَعْنِي ابْنَ آدَمَ - حَدَّثَنَا عَمَّارٌ، - وَهُوَ ابْنُ رُزَيْقٍ - عَنْ أَبِي إِسْحَاقَ، عَنِ الْبَرَاءِ، بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ آخِرُ سُورَةٍ أُنْزِلَتْ كَامِلَةً ‏.‏
