It was narrated that 'Abbas bin 'Abdul-Muttalib said:
"We used to come across groups of Quraish who would be talking, but they would stop talking (when we approached). We mentioned that to the Messenger of Allah and he said: 'What is the matter with people who talk, then when they see a man from my family they stop talking? By Allah, faith will not enter a person's heart until he loves them for the sake of Allah and because of their closeness to me.'"

حَدَّثَنَا مُحَمَّدُ بْنُ طَرِيفٍ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي سَبْرَةَ النَّخَعِيِّ، عَنْ مُحَمَّدِ بْنِ كَعْبٍ الْقُرَظِيِّ، عَنِ الْعَبَّاسِ بْنِ عَبْدِ الْمُطَّلِبِ، قَالَ كُنَّا نَلْقَى النَّفَرَ مِنْ قُرَيْشٍ وَهُمْ يَتَحَدَّثُونَ فَيَقْطَعُونَ حَدِيثَهُمْ فَذَكَرْنَا ذَلِكَ لِرَسُولِ اللَّهِ ﷺ فَقَالَ " مَا بَالُ أَقْوَامٍ يَتَحَدَّثُونَ فَإِذَا رَأَوُا الرَّجُلَ مِنْ أَهْلِ بَيْتِي قَطَعُوا حَدِيثَهُمْ وَاللَّهِ لاَ يَدْخُلُ قَلْبَ رَجُلٍ الإِيمَانُ حَتَّى يُحِبَّهُمْ لِلَّهِ وَلِقَرَابَتِهِمْ مِنِّي " .
