Sahih al-Bukhari, Hadith 7282 ⓘ
Narrated Hammam: Hudhaifa said, "O the Group of Al-Qurra! Follow the straight path, for then you have taken a great lead (and will be the leaders), but if you divert right or left, then you will go astray far away."
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ هَمَّامٍ، عَنْ حُذَيْفَةَ، قَالَ يَا مَعْشَرَ الْقُرَّاءِ اسْتَقِيمُوا فَقَدْ سُبِقْتُمْ سَبْقًا بَعِيدًا فَإِنْ أَخَذْتُمْ يَمِينًا وَشِمَالاً، لَقَدْ ضَلَلْتُمْ ضَلاَلاً بَعِيدًا.
