[Machine] Abbas ibn Abdul Muttalib entered the mosque one day and greeted them, but he noticed disapproval on their faces. So he returned to the Messenger of Allah in his house and said, "O Messenger of Allah, why do I see disapproval on the faces of the people when I enter the mosque?" The Messenger of Allah, ﷺ , came to the mosque until he entered it and said, "O people, you will not have faith and will not be believers until you love Abbas."  

دَخَلَ الْعَبَّاسُ بْنُ عَبْدِ الْمُطَّلِبِ يَوْمًا الْمَسْجِدَ فَسَلَّمَ عَلَيْهِمْ فَنَظَرَ إِلَى الْكَرَاهِيَةِ فِي وُجُوهِهِمْ فَرَجَعَ إِلَى رَسُولِ اللهِ ﷺ فِي بَيْتِهِ فَقَالَ يَا رَسُولَ اللهِ مَا لِي إِذَا دَخَلْتُ الْمَسْجِدَ أَرَى الْكَرَاهِيَةَ فِي وُجُوهِ النَّاسِ فَجَاءَ رَسُولُ اللهِ ﷺ حَتَّى دَخَلَ الْمَسْجِدَ فَقَالَ «يَا مَعْشَرَ النَّاسِ لَنْ تُؤْمِنُوا وَلَنْ تَكُونُوا مُؤْمِنِينَ حَتَّى تُحِبُّوا عَبَّاسًا»
