Musnad Ahmad 937:91

Bahz narrated to us, Sulayman ibn al-Mughirah narrated to us, from Humayd, from Abdullah ibn al-Samit, who said: Abu Dharr said: I said, "O Messenger of Allah, a man loves a people but is unable to perform their deeds?" He said, "You, O Abu Dharr, are with whom you love." He said: I said, "Indeed, I love Allah and His Messenger." He repeated it once or twice.
