On the authority of Abu Hamzah Anas bin Malik (may Allah be pleased with him) — the servant of the Messenger of Allah (peace and blessings of Allah be upon him) — that the Prophet (peace and blessings of Allah be upon him) said:

None of you [truly] believes until he loves for his brother that which he loves for himself. [Al-Bukhari] [Muslim]

عَنْ أَبِي حَمْزَةَ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللهُ عَنْهُ خَادِمِ رَسُولِ اللَّهِ صلى الله عليه و سلم عَنْ النَّبِيِّ صلى الله عليه و سلم قَالَ:

لَا يُؤْمِنُ أَحَدُكُمْ حَتَّى يُحِبَّ لِأَخِيهِ مَا يُحِبُّ لِنَفْسِهِ

. رَوَاهُ الْبُخَارِيُّ [رقم:13]، وَمُسْلِمٌ [رقم:45]. [رَوَاهُ الْبُخَارِيُّ] ، [وَمُسْلِمٌ]
