Musnad Ahmad 937:111

Waki’ and Ibn Ja’far narrated to us, they said: Shu’bah narrated to us, from Abu ‘Imran al-Jawni—Ibn Ja’far said: I heard Abu ‘Imran—from ‘Abdullah ibn al-Samit, the nephew of Abu Dharr, and Abu Dharr was his paternal uncle, from Abu Dharr, that he said: "O Messenger of Allah, what do you see regarding a man who does a deed, and the people love him for it?" He said: "That is the immediate glad tiding of the believer."
