Sahih al-Bukhari, Hadith 2786 ⓘ
Narrated Abu Sa`id Al-Khudri: Somebody asked, "O Allah's Messenger! Who is the best among the people?" Allah's Messenger replied "A believer who strives his utmost in Allah's Cause with his life and property." They asked, "Who is next?" He replied, "A believer who stays in one of the mountain paths worshipping Allah and leaving the people secure from his mischief."
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي عَطَاءُ بْنُ يَزِيدَ اللَّيْثِيُّ، أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ ـ رضى الله عنه ـ حَدَّثَهُ قَالَ قِيلَ يَا رَسُولَ اللَّهِ، أَىُّ النَّاسِ أَفْضَلُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مُؤْمِنٌ يُجَاهِدُ فِي سَبِيلِ اللَّهِ بِنَفْسِهِ وَمَالِهِ ". قَالُوا ثُمَّ مَنْ قَالَ " مُؤْمِنٌ فِي شِعْبٍ مِنَ الشِّعَابِ يَتَّقِي اللَّهَ، وَيَدَعُ النَّاسَ مِنْ شَرِّهِ ".
