عَنْ عَلِيٍّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”يَا عَلِيُّ إِنْ أَنْتَ وُلِّيتَ الْأَمْرَ بَعْدُ فَأَخْرِجْ أَهْلَ نَجْرَانَ مِنْ جَزِيرَةِ الْعَرَبِ“
It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: O Ali! If you attain leadership after me, then expel the people of Najran from the Arabian Peninsula.
