It is narrated from an elder of Banu Tamim, who says: Sayyiduna Ali (may Allah be pleased with him) delivered a sermon to us and said: A time of such hardship will come upon people that the prosperous will become extremely stingy with their possessions, even though they have not been commanded to do so; rather, Allah Almighty has said: { وَلَا تَنْسَوُا الْفَضْلَ بَیْنَکُمْ} … , and he also said: And evil people will be honored, good people will be humiliated, and people will take advantage of others’ hardships by buying and selling from them, even though the Messenger of Allah (peace and blessings be upon him) forbade selling by taking advantage of someone’s compulsion, selling by deception, and selling fruits before they have ripened.
