Sahih Muslim 45a
It is arrested on the authority of Anas b. Malik that the Prophet ﷺ observed: one amongst you believes (truly) till one likes for his brother or for his neighbour that which he loves for himself.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ، عَنِ النَّبِيِّ ﷺ قَالَ
" لاَ يُؤْمِنُ أَحَدُكُمْ حَتَّى يُحِبَّ لأَخِيهِ - أَوْ قَالَ لِجَارِهِ - مَا يُحِبُّ لِنَفْسِهِ " .
