Umar bin al-Khattab told me that he heard the Messenger of Allah ﷺ say: “I shall certainly expel the Jews and Christians from the Arabian Peninsula so that I will not leave anyone but Muslims.ʿ (Using translation from Aḥmad 201)
أَخْبَرَهُ أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ لَأُخْرِجَنَّ الْيَهُودَ وَالنَّصَارَى مِنْ جَزِيرَةِ الْعَرَبِ حَتَّى لَا أَذَرَ فِيهَا إِلَّا مُسْلِمًا
