Dhamdham bin Jaus says that once Hazrat Abu Hurairah (may Allah be pleased with him) said to me, "O Yamami, never say about any man that, 'By Allah, you will never be forgiven,' or, 'Allah will never admit you to Paradise.'" I said, "O Abu Hurairah, every one of us says this to his brother or companion in anger." He replied, "But still, you should not say it. I heard the Prophet (peace and blessings be upon him) say: 'There were two men among the Children of Israel; one was a great worshipper and the other was very sinful and immoral. The worshipper said to the sinner, 'By Allah, you will never be forgiven,' or, 'Allah will never admit you to Paradise.' Allah sent the Angel of Death to both of them, and he seized their souls, and both were brought together before Allah. Allah said to the sinner, 'Go by My mercy and enter Paradise,' and to the other He said, 'Did you know My decisions? Were you in control of what I possess?' Take him to Hell.' The Prophet (peace and blessings be upon him) said, 'By Him in Whose hand is the life of Abu al-Qasim (peace and blessings be upon him), he uttered only one word which destroyed his world and his Hereafter.'"
