[Machine] The Messenger of Allah ﷺ said, "O Abdullah, which bond of Islam is the strongest?" Abdullah replied, "I said, Allah and His Messenger know best." The Messenger of Allah ﷺ said, "Loving for the sake of Allah, hating for the sake of Allah. This was reported in the narrations of Al-Bara' and Ibn Abbas and Aisha." Imam Al-Shafi'i (may Allah have mercy on him) said, "Even if a person favors his people with love, as long as it does not lead him to treat others unfairly, this is a connection that is not based on tribalism. Every person has something that they love and something that they dislike."  

البيهقي:٢١٠٦٩أَخْبَرَنَا أَبُو بَكْرِ بْنُ فُورَكٍ أنبأ عَبْدُ اللهِ بْنُ جَعْفَرٍ ثنا يُونُسُ بْنُ حَبِيبٍ ثنا أَبُو دَاوُدَ ثنا الصَّعْقُ بْنُ حَزْنٍ عَنْ عَقِيلٍ الْجَعْدِيِّ عَنْ أَبِي إِسْحَاقَ عَنْ سُوَيْدِ بْنِ غَفَلَةَ عَنْ عَبْدِ اللهِ بْنِ مَسْعُودٍ ؓ قَالَ

قَالَ رَسُولُ اللهِ ﷺ يَا عَبْدَ اللهِ أِيُّ عُرَى الْإِسْلَامِ أَوْثَقُ ؟ قَالَ قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ الْوَلَايَةُ فِي اللهِ الْحَبُّ فِي اللهِ وَالْبُغْضُ فِي اللهِ رُوِيَ ذَلِكَ مِنْ حَدِيثِ الْبَرَاءِ وَابْنِ عَبَّاسٍ وَعَائِشَةَ ؓ قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ وَلَوْ خَصَّ امْرُؤٌ قَوْمَهُ بِالْمَحَبَّةِ مَا لَمْ يَحْمِلْ عَلَى غَيْرِهِمْ مَا لَيْسَ يَحِلُّ لَهُ فَهَذِهِ صِلَةٌ لَيْسَتْ بِعَصَبِيَّةٍ فَقَلَّ امْرُؤٌ إِلَّا وَفِيهِ مَحْبُوبٌ وَمَكْرُوهٌ
