Musnad Ahmad 1018:54

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, he said: I heard 'Urwah ibn 'Abdullah al-Ju'fi narrating from Abu Hasbah, or Ibn Hasbah, from a man who witnessed the Messenger of Allah, peace and blessings of Allah be upon him, delivering a sermon. He said: "Do you know who the *raqūb* (childless one) is?" They said: "The one who has no children." He said: "The *raqūb*, all the *raqūb*, the *raqūb*, all the *raqūb*, the *raqūb*, all the *raqūb*, is the one who has children, but they die and he has not sent anything [of good deeds] ahead of them." He said: "Do you know who the *sa'lūk* (pauper) is?" They said: "The one who has no wealth." The Prophet, peace and blessings of Allah be upon him, said: "The *sa'lūk*, all the *sa'lūk*, the *sa'lūk*, all the *sa'lūk*, is the one who has wealth, but he dies and has not sent anything [of good deeds] ahead of it." He said: Then the Prophet, peace and blessings of Allah be upon him, said: "What is the *sar'ah* (the one who is thrown)?" He said: They said: "The one who is thrown down [in wrestling]." He said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "The *sar'ah*, all the *sar'ah*, the *sar'ah*, all the *sar'ah*, is the man who becomes angry, and his anger intensifies, and his face reddens, and his hair stands on end, then he throws down his anger."
