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.  

سَمِعْتُ أَبَا مُوسَى الأَشْعَرِيَّ ؓ يَقُولُ قَدِمْتُ أَنَا وَأَخِي مِنَ الْيَمَنِ فَمَكُثْنَا حِينًا مَا نُرَى إِلاَّ أَنَّ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ رَجُلٌ مِنْ أَهْلِ بَيْتِ النَّبِيِّ ﷺ لِمَا نَرَى مِنْ دُخُولِهِ وَدُخُولِ أُمِّهِ عَلَى النَّبِيِّ ﷺ  

When I and my brother came from Yemen we used to consider Ibn Mas'ud and his mother amongst the members of the household. of Messenger of Allah ﷺ because of their visiting them frequently and staying there for long (periods of) time.  

قَدِمْتُ أَنَا وَأَخِي مِنَ الْيَمَنِ فَكُنَّا حِينًا وَمَا نُرَى ابْنَ مَسْعُودٍ وَأُمَّهُ إِلاَّ مِنْ أَهْلِ بَيْتِ رَسُولِ اللَّهِ ﷺ مِنْ كَثْرَةِ دُخُولِهِمْ وَلُزُومِهِمْ لَهُ  

"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."  

أَنَّهُ سَمِعَ أَبَا مُوسَى يَقُولُ لَقَدْ قَدِمْتُ أَنَا وَأَخِي مِنَ الْيَمَنِ وَمَا نُرَى حِينًا إِلاَّ أَنَّ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ رَجُلٌ مِنْ أَهْلِ بَيْتِ النَّبِيِّ ﷺ لِمَا نَرَى مِنْ دُخُولِهِ وَدُخُولِ أُمِّهِ عَلَى النَّبِيِّ ﷺ  

"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." (Using translation from Tirmidhī 3806)   

أَنَّهُ سَمِعَ أَبَا مُوسَى يَقُولُ «لَقَدْ قَدِمْتُ أَنَا وَأَخِي مِنَ الْيَمَنِ فَمَكَثْنَا حِينًا لَا نَرَى إِلَّا أَنَّ عَبْدَ اللهِ بْنَ مَسْعُودٍ مِنْ أَهْلِ بَيْتِ النَّبِيِّ ﷺ مِنْ دُخُولِهِ عَلَى النَّبِيِّ ﷺ»  

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
