What is meant by the authentication of Ibn Masoud (may Allah be pleased with him) in the Hadith: "And whatever Ibn Masoud narrates to you, then authenticate it"? And do we authenticate everything he says regarding the interpretation of verses and statements, or only in specific matters?

In the noble prophetic hadith: "Whatever Ibn Mas'ud narrates to you, believe it," and in another narration: "Adhere to the covenant of Ibn Mas'ud," and in a third: "I am pleased for my Ummah with what Ibn Umm Abd is pleased for it." These hadiths indicate the virtue of Ibn Mas'ud and his lofty scholarly status. They call for taking what he narrates from the texts of revelation, what he deduces through his ijtihad regarding legal rulings, and what he advises and preaches to the Ummah. This was the methodology of the Companions, the Tabi'in, and those who came after them in referring to his sayings and fatwas.
