I heard ʿAli ؓ say: I heard the Messenger of Allah ﷺ say: “There is no Prophet who came before me but he was given seven chiefs, advisors and nobles, but I have been given fourteen chiefs, advisers and nobles: seven from Quraish and seven from among the Muhajireen.”
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ لَيْسَ مِنْ نَبِيٍّ كَانَ قَبْلِي إِلا قَدْ أُعْطِيَ سَبْعَةَ نُقَبَاءَ وُزَرَاءَ نُجَبَاءَ وَإِنِّي أُعْطِيتُ أَرْبَعَةَ عَشَرَوَزِيرًا نَقِيبًا نَجِيبًا سَبْعَةً مِنْ قُرَيْشٍ وَسَبْعَةً مِنَ الْمُهَاجِرِينَ
