Ibrâhîm b. Maysurah reports that Tâwûs said to him, “You better get married or I will say to you what ‘Umar b. Al-Khattâb said to Abû Al-Zawâ`id: ‘Nothing but incapability or sinfulness is preventing you from getting married!’”
Al-Dhahabî, Siyar A’lâm Al-Nubalâ`, in his biography of Tâwûs.
Tâwûs b. Kaysân was a great scholar and ascetic. He was the most renowned scholar of Yemen during his time. He is regarded as one of the senior companions and students of Ibn ‘Abbâs, and reports narrations from a number of other Companions.
