وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِأَبِي ذَرٍّ: «يَا أَبَا ذَرٍّ أَيُّ عُرَى الْإِيمَانِ أَوْثَقُ؟» قَالَ: اللَّهُ وَرَسُولُهُ أَعْلَمُ. قَالَ: «الْمُوَالَاةُ فِي اللَّهِ وَالْحُبُّ فِي اللَّهِ وَالْبُغْضُ فِي اللَّهِ» . رَوَاهُ الْبَيْهَقِيّ فِي «شعب الْإِيمَان»
Ibn Abbas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said to Abu Dharr (may Allah be pleased with him): "Abu Dharr! Which part (aspect) of faith is the strongest and most firm?" He replied, "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) said: "Loving and supporting each other for the sake of Allah, loving for the sake of Allah, and harboring aversion for the sake of Allah." Weak, narrated by Al-Bayhaqi in Shu'ab al-Iman.
