Sahih Muslim 42bBook 1, Hadith 71
وَحَدَّثَنِيهِ إِبْرَاهِيمُ بْنُ سَعِيدٍ الْجَوْهَرِيُّ، حَدَّثَنَا أَبُو أُسَامَةَ، قَالَ حَدَّثَنِي بُرَيْدُ بْنُ عَبْدِ اللَّهِ، بِهَذَا الإِسْنَادِ قَالَ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَىُّ الْمُسْلِمِينَ أَفْضَلُ فَذَكَرَ مِثْلَهُ .
Ibrahim b. Sa'id al-Jauhari has narrated this hadith with the same words in addition to these. The Messenger of Allah (may peace and blessings be upon him) was asked as to who amongst the Muslims is better, and the rest of the hadith was narrated like this.
