حَدَّثَنَا حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ ، عَنْ مُعْتَمِرِ بْنِ سُلَيْمَانَ ، عَنْ أَبِيهِ ، حَدَّثَنَا أَبُو عِمْرَانَ الْجَوْنِيُّ ، عَنْ جُنْدَبٍ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حَدَّثَ : " أَنَّ رَجُلًا ، قَالَ : وَاللَّهِ لَا يَغْفِرُ اللَّهُ لِفُلَانٍ ، وَإِنَّ اللَّهَ تَعَالَى ، قَالَ : مَنْ ذَا الَّذِي يَتَأَلَّى عَلَيَّ أَنْ لَا أَغْفِرَ لِفُلَانٍ ، فَإِنِّي قَدْ غَفَرْتُ لِفُلَانٍ ، وَأَحْبَطْتُ عَمَلَكَ " أَوْ كَمَا قَالَ .
Jundub reported that Allah's Messenger (ﷺ) stated that a person said: 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).
