Al-Matalib al-'Aliyah 4066 — The virtue of Ibn Mas'ud

It is narrated from al-Qasim bin Abd al-Rahman (may Allah have mercy on him) that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) spoke in the presence of the Prophet (peace and blessings be upon him). He praised and glorified Allah Almighty, and then said: 'Raditu billahi rabban, wa bil-Islami dinan, wa bi-Muhammadin rasulan' (I am pleased (with all my heart) with Allah as Lord, with Islam as religion, and with Muhammad (peace and blessings be upon him) as Messenger). Then he said (to the Companions): "I am pleased for you with what Allah and His Messenger are pleased with, and I dislike for you what Allah and His Messenger dislike." Then the Prophet (peace and blessings be upon him) said: "I am pleased for my Ummah with what Ibn Umm Abd (Abdullah bin Mas'ud) is pleased with for them."
Imam al-Hakim transmitted this report in al-Mustadrak and Imam al-Dhahabi declared it sahih (authentic); moreover, it has supporting reports in other books of hadith as well.
