The Messenger of Allah [SAW] said: "By the One in Whose hand is the soul of Muhammad, none of you has believed until he loves for his brother what he loves for himself of goodness." (Using translation from Nasāʾī 5017)
أَنَّ نَبِيَّ اللهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَا يُؤْمِنُ عَبْدٌ حَتَّى يُحِبَّ لِأَخِيهِ مَا يُحِبُّ لِنَفْسِهِ مِنَالْخَيْرِ
