From among the people, Ibn Umm Abd (Abdullah b. Masud) greatly resembled Messenger of Allah ﷺs in solemn gate and good appearance of piety and in calmness and sobriety from the time he goes out of his house till he returns to it. But we do not know how he behaves with his family when he is alone with them.  

إِنَّ أَشْبَهَ النَّاسِ دَلاًّ وَسَمْتًا وَهَدْيًا بِرَسُولِ اللَّهِ ﷺ لاَبْنُ أُمِّ عَبْدٍ مِنْ حِينَ يَخْرُجُ مِنْ بَيْتِهِ إِلَى أَنْ يَرْجِعَ إِلَيْهِ لاَ نَدْرِي مَا يَصْنَعُ فِي أَهْلِهِ إِذَا خَلاَ  

[Machine] Hudhaifah said, "Indeed, the closest person in resemblance, guidance, justice, and speech to the Messenger of Allah ﷺ from the time he leaves his house until he returns, and I don't know what he does with his family, is Abdullah bin Mas'ood. And by Allah, the fortunate ones from the companions of Muhammad ﷺ know that Ibn Mas'ood is among the closest to them and a means for them."  

حُذَيْفَةُ «إِنَّ أَشْبَهَ النَّاسِ هَدْيًا وَدَلًّا وَقَضَاءً وَخُطْبَةً بِرَسُولِ اللهِ ﷺ مِنْ حِينِ يَخْرُجُ مِنْ بَيْتِهِ إِلَى أَنْ يَرْجِعَ وَلَا أَدْرِي مَا يَصْنَعُ فِي أَهْلِهِ لَعَبْدُ اللهِ بْنُ مَسْعُودٍ وَاللهِ إِنَّ الْمَحْظُوظِينَ مِنْ أَصْحَابِ مُحَمَّدٍ ﷺ لَيَعْلَمُونَ أَنَّ ابْنَ مَسْعُودٍ مِنْ أَقْرَبِهِمْ وَسِيلَةً»
