Sahih al-Bukhari
Sahih al-Bukhari 51
حَدَّثَنَا إِبْرَاهِيمُ بْنُ حَمْزَةَ، قَالَ حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنْ صَالِحٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، أَخْبَرَهُ قَالَ أَخْبَرَنِي أَبُو سُفْيَانَ، أَنَّ هِرَقْلَ، قَالَ لَهُ سَأَلْتُكَ هَلْ يَزِيدُونَ أَمْ يَنْقُصُونَ، فَزَعَمْتَ أَنَّهُمْ يَزِيدُونَ، وَكَذَلِكَ الإِيمَانُ حَتَّى يَتِمَّ. وَسَأَلْتُكَ هَلْ يَرْتَدُّ أَحَدٌ سَخْطَةً لِدِينِهِ بَعْدَ أَنْ يَدْخُلَ فِيهِ، فَزَعَمْتَ أَنْ لاَ، وَكَذَلِكَ الإِيمَانُ حِينَ تُخَالِطُ بَشَاشَتُهُ الْقُلُوبَ، لاَ يَسْخَطُهُ أَحَدٌ.
Ibrahim ibn Hamza narrated to us. He said: Ibrahim ibn Sa'd narrated to us, from Salih, from Ibn Shihab, from Ubaydullah ibn Abdullah, that Abdullah ibn Abbas informed him, saying: Abu Sufyan informed me that Heraclius said to him: ‘I asked you whether they were increasing or decreasing, and you claimed that they were increasing. Such is faith until it is complete. I asked you whether anyone turns away from his religion in resentment after entering it, and you claimed that no one does. Such is faith when its delight mingles with hearts; no one resents it.’
Translation notes
The English witness identifies ‘they’ as the followers of Muhammad and adds explanatory phrases about faith being true or complete in all respects. Those expansions are not in this Arabic passage.
