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.  

مسلم:١٦١٨dحَدَّثَنَا 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
