It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Amin, Amin, Amin." It was said to him (peace and blessings be upon him): "O Messenger of Allah! You did not used to do this?" So he (peace and blessings be upon him) said: "Jibril (peace be upon him) said to me: May the nose of that servant be rubbed in dust, or he said: may he be far removed, upon whom the month of Ramadan came and he was not forgiven. So I said: Amin. Then he said: May the nose of that servant be rubbed in dust, or he said: may he be far removed, who found his parents, or one of them, and they could not get him into Paradise. So I said: Amin. Then he said: May the nose of that servant be rubbed in dust, or he said: may he be far removed, before whom you were mentioned and he did not send blessings upon you. So I said: Amin."
