(4) Another addition in manuscript Q, not found in B or H, reads: “Wahb ibn Munabbih met several Companions and narrated from Ibn ʿAbbas, Jabir, and al-Nuʿman ibn Bashir; he transmitted from Muʿadh ibn Jabal, Abu Hurayra, and Tawus; and he received from several Tabiʿin. He said, ‘The example of one who learns knowledge but does not act upon it is like that of a physician who has a remedy but does not use it.’ From Munir, the mawla (freedman) of al-Fadl ibn Abi ʿIyash: ‘I was sitting with Wahb when a man came and told him, “I passed by so-and-so and he was insulting you.” Wahb became angry and said, “Has not Satan found another messenger than you?” Before I left, the same reviler returned, greeted Wahb, who responded, extended his hand, shook it, and seated him at his side’ (Abu Nuʿaym, Hilyat al-Awliyaʾ, 4:71; Ibn al-Jawzi, Sifat al-Safwa, 2:295). Ibn al-Tawus related, ‘I heard Wahb say, “O son of Adam, attend to your religion, for your provision will come to you.”’ (Abu Nuʿaym, Hilyat al-Awliyaʾ, 4:72). Wahb also said, ‘The inhabitants of Hell were clothed, yet nakedness would have been better for them; they were fed, yet hunger would have been better for them; they were granted life, yet death would have been better for them’ (Abu Nuʿaym, Hilyat al-Awliyaʾ, 4:71). He added that David (peace be upon him) prayed, ‘O Allah, any poor man who asks a rich man and is turned away—so I ask You: when he calls upon You, do not respond; and if he asks You, do not give him’ (Abu Nuʿaym, Hilyat al-Awliyaʾ, 4:71). And he said, ‘I read in some of the Books of Allah: “O son of Adam, there is no benefit in knowing what you did not know if you do not act upon what you have known; like a man who gathered firewood, bundled it, then set out to carry it but could not, so he added more to it”’ (Abu Nuʿaym, Hilyat al-Awliyaʾ, 4:71).
