The extremists are quick to accuse their opponents of takfir in ostentation disobedience to Allah. They forget that which the Prophet (PBUH) reported regarding two of the Bani Israel one who was a worshipper and the other was sinner, the worshiper said one day: Allah would not forgive such and such (person). Thereupon Allah the Exalted and Glorious, said: Who is he who adjures about Me that I would not grant pardon to so and so; I have granted pardon to so and so and blotted out his deeds (who took an oath that I would not grant pardon to him).  “He said:” God does not forgive Allah for the sake of Allah, and He does not forgive Allah for the sake of Allah, God Almighty said: Who is the one who rises to me and swears that I will not forgive for this, I have forgiven you and I foiled your work) (Narrated by Muslim)
