Messenger of Allah, why is it that you select (your wife) from among the Quraish, but you ignore us (the nearest of the kin)? Thereupon he said: Have you anything for me (a suitable match for me)? I said; Yes, the daughter of Hamza, whereupon Messenger of Allah ﷺ said: She is not lawful for me, for she is the daughter of my brother by reason of fosterage.
قُلْتُ يَا رَسُولَ اللَّهِ مَا لَكَ تَنَوَّقُ فِي قُرَيْشٍ وَتَدَعُنَا فَقَالَ وَعِنْدَكُمْ شَىْءٌ قُلْتُ نَعَمْ بِنْتُ حَمْزَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّهَا لاَ تَحِلُّ لِي إِنَّهَا ابْنَةُ أَخِي مِنَ الرَّضَاعَةِ
