Musnad Abu Ya'la al-Mawsili 1:98

Abu Khaythama narrated to us, Yahya bin Sa'id narrated to us, from Isma'il bin Abi Khalid, who said: Abu Bakr bin Abi Zuhayr narrated to me, from Abu Bakr al-Siddiq, that he said: "O Messenger of Allah, how is righteousness after this verse: 'Whoever does evil will be recompensed for it' [Surah An-Nisa: 123]? Every evil we do, we will be recompensed for it?" He said: "May Allah have mercy on you, O Abu Bakr. Do you not fall ill? Do you not become weary? Do you not suffer hardship? That is what you are recompensed for."
