Anas b. Malik reported that the Messenger of Allah ﷺ gathered the Ansar and said: Is there someone alien among you? They said: No, but only the son of our sister. Upon this the Messenger of Allah ﷺ said: The son of the sister of the people is included among the tribe, and (farther) said: The Quraish have recently abandoned Jahillyya and have just been delivered from distress;
I, therefore, intend to help them and conciliate them. Don't you feel happy that the people should return with worldly riches and you return with the Messenger of Allah to your houses? (So far as my love for you is concerned I should say) if the people were to tread a valley and the Ansar tread a narraw path (in a mountain) I would tread the narrow path of the Ansar.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، أَخْبَرَنَا شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ جَمَعَ رَسُولُ اللَّهِ ﷺ الأَنْصَارَ فَقَالَ " أَفِيكُمْ أَحَدٌ مِنْ غَيْرِكُمْ " . فَقَالُوا لاَ إِلاَّ ابْنُ أُخْتٍ لَنَا . فَقَالَ رَسُولُ اللَّهِ ﷺ " إِنَّ ابْنَ أُخْتِ الْقَوْمِ مِنْهُمْ " . فَقَالَ " إِنَّ قُرَيْشًا حَدِيثُ عَهْدٍ بِجَاهِلِيَّةٍ وَمُصِيبَةٍ وَإِنِّي أَرَدْتُ أَنْ أَجْبُرَهُمْ وَأَتَأَلَّفَهُمْ أَمَا تَرْضَوْنَ أَنْ يَرْجِعَ النَّاسُ بِالدُّنْيَا وَتَرْجِعُونَ بِرَسُولِ اللَّهِ إِلَى بُيُوتِكُمْ لَوْ سَلَكَ النَّاسُ وَادِيًا وَسَلَكَ الأَنْصَارُ شِعْبًا لَسَلَكْتُ شِعْبَ الأَنْصَارِ " .
