Musannaf Ibn Abi Shaybah 40367 — Reports on the tribulation

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: Indeed, the first kind of jihad in which you will be overpowered is jihad with the hands, then your jihad with the tongue, then jihad with the heart. So any heart that does not regard good as good and does not consider evil as evil will be turned upside down, and its upper side will be made its lower side.
