وَعَنْ أَنَسٍ رضى الله عنه عَنْ
اَلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «وََالَّذِي نَفْسِي بِيَدِهِ لَا يُؤْمِنُ عَبْدٌ حَتَّى يُحِبَّ لِجَارِهِ (أَوْ لِأَخِيهِ) مَا يُحِبُّ لِنَفْسِهِ»
“By Him in Whose Hand my soul is, a slave of Allah does not truly believe till he wishes for his neighbor what he wishes for himself.” Agreed upon.
