Malik said, Umar ibn al-Khattab expelled the Jews from Najran as well.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَجْتَمِعُ دِينَانِ فِي جَزِيرَةِ الْعَرَبِ قَالَ مَالِكٌ قَالَ ابْنُ شِهَابٍ فَفَحَصَ عَنْ ذَلِكَ عُمَرُ بْنُ الْخَطَّابِ ؓ حَتَّى أَتَاهُ الثَّلَجُ وَالْيَقِينُ عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ لَا يَجْتَمِعُ دِينَانِ فِي جَزِيرَةِ الْعَرَبِ فَأَجْلَى يَهُودَ خَيْبَرَ قَالَ مَالِكٌ قَدْ أَجْلَى عُمَرُ بْنُ الْخَطَّابِ ؓ يَهُودَ نَجْرَانَ وَفَدَكَ
