To swear and to take Oath (binding) upon Allah
It is narrated from Jundub bin Abdullah (R.A.) that Allah’s Messenger (SAW) said:
A man said: ‘By Allah! Would not forgive such and such (person).’ Thereupon Allah the Exalted and Glorious said: ‘Who is he who swears about Me that I would not grant pardon to so-and-so? I have granted pardon to so-and-so and blotted out your (the swearer’s) deeds.” (Muslim)
According to another Hadith from Abu Hurairah (R.A.), the man who said it, was a faithful worshipper. Abu Hurairah (R.A.) said:
“His one statement destroyed his life in this world and the Hereafter.”
