Musnad Abu Ya'la al-Mawsili 1:96

Muhammad ibn Abi Bakr al-Muqaddami narrated to us, Yahya and Uthman ibn Ali narrated to us, from Isma'il ibn Abi Khalid, from Abu Bakr ibn Abi Zuhayr, from Abu Bakr al-Siddiq, who said: I said, "O Messenger of Allah, how can there be righteousness after this verse: 'Whoever does evil will be recompensed for it' (Surah An-Nisa, verse 123)? We are surely to be recompensed for everything that happens from us." He said, "May Allah have mercy on you, O Abu Bakr. Do you not grieve? Do you not suffer fatigue? Does hardship not afflict you?" I said, "Yes." He said, "Then this is what you are recompensed for."
