Musannaf Ibn Abi Shaybah

Hazrat Tamim bin Hazlam, may Allah have mercy on him, says that I have attended the gatherings of many companions of Muhammad, may Allah be pleased with him. The gatherings of Hazrat Abu Bakr, may Allah be pleased with him, and Hazrat Umar, may Allah be pleased with him. But I have not seen anyone more disinterested in the world and more desirous of the Hereafter than Ibn Mas'ud, may Allah be pleased with him. O Abdullah bin Mas'ud, may Allah be pleased with him, nor do I wish that on the Day of Judgment I should be with them instead of you, may Allah be pleased with him.
