‘Amr bin Maimun said: “I used to visit Ibn Mas’ud every Thursday afternoon, but he never uttered the words: ‘The Messenger of Allah (p.b.u.h) said.’ Then one evening, he said: ‘The Messenger of Allah (P.B.U.H) said,’ then he let his head hang down.” He said “I looked at him and saw that his shirt was unfastened; his eyes were filled with tears, and his veins were bulging out (with fera). He said: ‘Or more than that, or less than that, or close to that, or something similar.’ (Sahih)
