Sahih Muslim 171

Arabic

وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ وَالَّذِي نَفْسِي بِيَدِهِ لاَ يُؤْمِنُ عَبْدٌ حَتَّى يُحِبَّ لِجَارِهِ - أَوْ قَالَ لأَخِيهِ - مَا يُحِبُّ لِنَفْسِهِ ‏"‏ ‏.‏
