عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ فِي خُطْبَتِهِ وَهُوَ مُسْنِدٌ ظَهْرَهُ إِلَى الْكَعْبَةِ لَا يُقْتَلُ مُسْلِمٌ بِكَافِرٍ وَلَا ذُو عَهْدٍ فِي عَهْدِهِ
Narrated by Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said in one of his addresses, while he was sitting leaning against the Ka'bah: "A Muslim will not be killed in retaliation for a disbeliever, nor will a dhimmi (non-Muslim under Muslim protection) be killed during his covenant."
