The Prophet (may Allah's peace and blessings be upon him) informed that whoever frequently and unjustly curses others deserves two punishments: First: He will not be a witness on the Day of Judgment over the nations that the divine messages were conveyed to them through their messengers; his testimony will not be accepted in this world due to his defiant disobedience; and he will not be granted martyrdom, which is dying in the way of Allah. Second: He will not be able to intercede on the Day of Judgment when the believers intercede for their brothers who have deserved the Hellfire.
