Sahih Adab al-Mufrad

943/1238 (Hasan al-Isnad) from al-Sa'ib [ هو ابن يزيد], from Umar who said: "Sometimes men, Quraysh, would sit at the door of Ibn Mas'ud, and when the shade shifted, he would say: 'Stand up(1), for what remains is for the devil,'" and then he would not pass by anyone except that he would make him stand. He said: Then while he was like that, it was said: This is the freedman of Banu al-Hasshas reciting poetry, so he called him and said: How did you say it? He said: "Bid Salayma farewell if you set out as a warrior... Gray hair and Islam are enough to deter a man." He said: "Enough for you, you have spoken the truth, you have spoken the truth."
