عَنْ جُبَيْرِ بْنِ مُطْعِمٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: ”إِنَّ لِلْقُرَشِيِّ مِثْلَيْ قُوَّةِ الرَّجُلِ مِنْ غَيْرِ قُرَيْشٍ.“ فَقِيلَ لِلزُّهْرِيِّ: مَا عَنَى بِذَلِكَ؟ قَالَ: نُبْلَ الرَّأْيِ.
It is narrated from Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A Qurayshi has twice the strength of a non-Qurayshi. Zuhri was asked: What is meant by this hadith? He said: Soundness of judgment.
