Sunan of Abu Dawood Book 20, Hadith 3033

حَدَّثَنَا مَحْمُودُ بْنُ خَالِدٍ، حَدَّثَنَا عُمَرُ، - يَعْنِي ابْنَ عَبْدِ الْوَاحِدِ - قَالَ قَالَ سَعِيدٌ - يَعْنِي ابْنَ عَبْدِ الْعَزِيزِ - جَزِيرَةُ الْعَرَبِ مَا بَيْنَ الْوَادِي إِلَى أَقْصَى الْيَمَنِ إِلَى تُخُومِ الْعِرَاقِ إِلَى الْبَحْرِ ‏.‏ قَالَ أَبُو دَاوُدَ قُرِئَ عَلَى الْحَارِثِ بْنِ مِسْكِينٍ وَأَنَا شَاهِدٌ أَخْبَرَكَ أَشْهَبُ بْنُ عَبْدِ الْعَزِيزِ قَالَ قَالَ مَالِكٌ عُمَرُ أَجْلَى أَهْلَ نَجْرَانَ وَلَمْ يُجْلَوْا مِنْ تَيْمَاءَ لأَنَّهَا لَيْسَتْ مِنْ بِلاَدِ الْعَرَبِ فَأَمَّا الْوَادِي فَإِنِّي أَرَى إِنَّمَا لَمْ يُجْلَ مَنْ فِيهَا مِنَ الْيَهُودِ أَنَّهُمْ لَمْ يَرَوْهَا مِنْ أَرْضِ الْعَرَبِ ‏.‏

Sa'id bin Abd Al ‘Aziz said "Arabia lies between Al Wadi to the extremes of the Yemen extending to the frontiers of Al Iraq and the sea." Abu Dawud said "This tradition was read out to Al Harith bin Miskin while I was a witness". Ashhab bin ‘Abd Al Aziz reported it to you on the authority of Malik who said ‘Umar expelled the people of Najran, but he did not expel (them) from Taima. For it did not fall within the territory of Arabia. As for Al Wadi, I think the Jews were not expelled from there. They did not think it a part of the land of Arabia
