It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) cursed the one who consumes usury, the one who gives it, its two witnesses, the one who writes it, the one who fills sesame, the one for whom sesame is filled, the one who performs halalah, the one for whom halalah is performed, and the one who withholds charity or zakat. And the Prophet (peace and blessings be upon him) used to prohibit wailing as well.
