Hadeeth Newsflash

Reported by Jundub bin `Abdullah (RA): The Messenger of Allah (peace be upon him) said, "Once someone said: `By Allah! Allah will not forgive such and such (a person).' Thereupon Allah, the Exalted and the Glorious, said: `Who is he who takes an oath in My Name that I will not grant pardon to so-and-so? I have granted pardon to so-and-so and rendered your good deeds fruitless.''' [Muslim]
