My brother and I came from Yemen, and for some time we continued to consider ʿAbdullah bin Masʿud as one of the members of the family of the Prophet ﷺ because we used to see him and his mother going in the house of the Prophet ﷺ very often. (Using translation from Bukhārī 3763)
سَمِعْتُ أَبَا مُوسَى الْأَشْعَرِيَّ يَقُولُ لَقَدْ قَدِمْتُ أَنَا وَأَخِي مِنَ الْيَمَنِ فَمَكَثْنَا حِينًا مَا نَرَى إِلَّا أَنَّ عَبْدَ اللهِ بْنَ مَسْعُودٍ رَجُلٌ مِنْ أَهْلِ بَيْتِ النَّبِيِّ ﷺ مِمَّا نَرَى مِنْ دُخُولِهِ وَدُخُولِ أُمِّهِ عَلَى النَّبِيِّ ﷺ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ إِبْرَاهِيمَ بْنِ يُوسُفَ
