Hadith Qudsi 31:
On the authority of Jundub (may Allah
[The Most High] be pleased with him), who said that the Messenger of Allah [The
Most High] related:
A man said: By Allah, Allah will not forgive So-and-so. At this Allah the Almighty
said: Who is he who swears by Me that I
will not forgive So-and-so? Verily I have forgiven So-and-so and have nullified
your [own good] deeds (1) (or as he said [it]).
(1) A similar Hadith, which is given by
Abu Dawud, indicates that the person referred to was a goldly man whose previous
good deeds were brought to nought through presuming to declare that Allah would not forgive someone's bad deeds.
It was related by Muslim.
