عَنْ أَبِي إِدْرِيسَ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ مُعَاوِيَةَ يَعْنِي ابْنَ أَبِي سُفْيَانَ وَكَانَ قَلِيلَ الْحَدِيثِ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَهُوَ يَقُولُ كُلُّ ذَنْبٍ عَسَى اللَّهُ أَنْ يَغْفِرَهُ إِلَّا الرَّجُلَ يَمُوتُ كَافِرًا وَالرَّجُلَ يَقْتُلُ مُؤْمِنًا مُتَعَمِّدًا
Narrated from Sayyiduna Muawiyah bin Abi Sufyan, may Allah be pleased with him, who was among those who narrated few hadiths, that the Messenger of Allah, peace and blessings be upon him, said: It is possible that Allah Almighty may forgive every sin, except for the person who dies in a state of disbelief and the one who deliberately kills a believer.
