It is narrated from a man of Banu Amir who says that Hazrat Ali (may Allah be pleased with him) said: I fear only two things for you: long hopes and following desires. Because having long hopes makes one forget the Hereafter, and following desires becomes an obstacle to the truth. Surely, the world is turning its back and departing, and the Hereafter is coming. And each of them has children. So be children of the Hereafter. For today there is action, there is no reckoning, and tomorrow there will be reckoning, there will be no action.
