كتاب المناقب
Read the English translation first, with the original Arabic directly underneath.
Narrated Tawus:
Ibn `Abbas recited the Qur'anic Verse:--'Except to be kind to me for my kin-ship to you--" (42:23) Sa`id bin Jubair said, "(The Verse implies) the kinship of Muhammad." Ibn `Abbas said, "There was not a single house (i.e. sub-tribe) of Quraish but had a kinship to the Prophet (ﷺ) and so the above Verse was revealed in this connection, and its interpretation is: 'O Quraish! You should keep good relation between me (i.e. Muhammad) and you."
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، حَدَّثَنِي عَبْدُ الْمَلِكِ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما – {إِلاَّ الْمَوَدَّةَ فِي الْقُرْبَى} قَالَ فَقَالَ سَعِيدُ بْنُ جُبَيْرٍ قُرْبَى مُحَمَّدٍ صلى الله عليه وسلم. فَقَالَ إِنَّ النَّبِيَّ صلى الله عليه وسلم لَمْ يَكُنْ بَطْنٌ مِنْ قُرَيْشٍ إِلاَّ وَلَهُ فِيهِ قَرَابَةٌ، فَنَزَلَتْ عَلَيْهِ إِلاَّ أَنْ تَصِلُوا قَرَابَةً بَيْنِي وَبَيْنَكُمْ.
