Sahih al-Bukhari 3763

"My brother and I arrived from Yemen, and we did not see a period except that we thought 'Abdullah bin Mas'ud was a man from the people of the house of the Prophet (ﷺ), due to what we would see of him entering, and his mother's entering, upon the Prophet (ﷺ)."

لَقَدْ قَدِمْتُ أَنَا وَأَخِي، مِنَ الْيَمَنِ وَمَا نُرَى حِينًا إِلاَّ أَنَّ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ رَجُلٌ مِنْ أَهْلِ بَيْتِ النَّبِيِّ صلى الله عليه وسلم لِمَا نَرَى مِنْ دُخُولِهِ وَدُخُولِ أُمِّهِ عَلَى…

My brother and I came from the Yemen and for quite a time we had no idea that `Abdallah b. Mas'ud was other than a member of the Prophet's family because of seeing how frequently he and his mother went in to visit the Prophet. (Bukhari and Muslim.)

وَعَنْ أَبِي مُوسَى الْأَشْعَرِيِّ قَالَ: قَدِمْتُ أَنَا وَأَخِي مِنَ الْيَمَنِ فَمَكَثْنَا حِينًا مَا نَرَى إِلَّا أَنَّ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ رَجُلٌ مِنْ أَهْلِ بَيْتِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ…
