حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ حَدَّثَنَا سُفْيَانُ قَالَ سَأَلْتُ الْأَعْمَشَ فَقَالَ عَنْ زَيْدِ بْنِ وَهْبٍ سَمِعْتُ حُذَيْفَةَ يَقُولُ حَدَّثَنَا رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّ الْأَمَانَةَ نَزَلَتْ مِنْ السَّمَائِ فِي جَذْرِ قُلُوبِ الرِّجَالِ وَنَزَلَ الْقُرْآنُ فَقَرَئُوا الْقُرْآنَ وَعَلِمُوا مِنْ السُّنَّةِ
صحیح بخاری · Hadith 7276
Narrated Hudhaifa: Allah's Apostle said to us, "Honesty descended from the Heavens and settled in the roots of the hearts of men (faithful believers), and then the Qur'an was revealed and the people read the Qur'an, (and learnt it from it) and also learnt it from the Sunna." Both Qur'an and Sunna strengthened their (the faithful believers') honesty. (See Hadith No. 208)
