Saad Bin Abi Waqas: Punishment for cursing the Sahaba

Saad bin Abi Waqas (may Allah be pleased with him) one day heard a man grumpling; when he listened closely to what he was saying he realized he was abusing Ali, Talhah and Zubair (may Allah be pleased with them). He told him to stop, but he would not listen and continued. Finally, Saad bin Abi Waqas (may Allah be pleased with him) lost his temper, and said if he did not control his tongue he would put a curse on him. Arrogantly the man told him that he was arrogating powers to himself and he asked him if he thought he was a Prophet..
