"I swear to you by Allah! You know that the Messenger of Allah ﷺ said: 'The blood of a Muslim man is not lawful, except for one of three (cases):Illegitimate sexual relations after Ihsan (having been married), or apostasy after Islam, or taking a life without right, for which he is killed.' By Allah! I have never committed illegitimate sexual relations, not during Jahiliyyah nor during Islam, and I have not committed apostasy since I gave my pledge to the Messenger of Allah ﷺ, and I have not taken a life that Allah had made unlawful. So for what do you fight me?"'
أَنَّ عُثْمَانَ بْنَ عَفَّانَ أَشْرَفَ يَوْمَ الدَّارِ فَقَالَ أَنْشُدُكُمُ اللَّهَ أَتَعْلَمُونَ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ دَمُ امْرِئٍ مُسْلِمٍ إِلاَّ بِإِحْدَى ثَلاَثٍ زِنًا بَعْدَ إِحْصَانٍ أَوِ ارْتِدَادٍ بَعْدَ إِسْلاَمٍ أَوْ قَتْلِ نَفْسٍ بِغَيْرِ حَقٍّ فَقُتِلَ بِهِ فَوَاللَّهِ مَا زَنَيْتُ فِي جَاهِلِيَّةٍ وَلاَ فِي إِسْلاَمٍ وَلاَ ارْتَدَدْتُ مُنْذُ بَايَعْتُ رَسُولَ اللَّهِ ﷺ وَلاَ قَتَلْتُ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ فَبِمَ تَقْتُلُونَنِي
