I set out with al-Ashtar to go to ‘Ali ؓ . We said: Did the Prophet of Allah ﷺ tell you something that he did not tell to all the people? He said: No, except what is in this document. He [the narrator] said: A document in the sheath of this sword. In it was said: “The believers are equal in respect of blood and they are one against their enemies; protection given even by the least among them is to be honoured, but no believer is to be killed (in retaliation) for a disbeliever and no one who has a covenant is to be killed during the covenant. Whoever commits an offence or gives refuge to an offender, upon him be the curse of Allah, the angels and all the people.ʿ (Using translation from Aḥmad 993)
أَتَيْنَا عَلِيًّا ؓ أَنَا وَجَارِيَةُ بْنُ قُدَامَةَ السَّعْدِيُّ فَقُلْنَا هَلْ مَعَكَ عَهْدٌ مِنْ رَسُولِ اللهِ ﷺ؟ فَقَالَ لَا إِلَّا مَا فِي قِرَابِ سَيْفِي فَأَخْرَجَ لَنَا مِنْهُ كِتَابًا فَقَرَأَهُ فَإِذَا فِيهِ الْمُسْلِمُونَ تَتَكَافَأُ دِمَاؤُهُمْ وَيَسْعَى بِذِمَّتِهِمْ أَدْنَاهُمْ وَهُمْ يَدٌ عَلَى مَنْ سِوَاهُمْ أَلَا لَا يُقْتَلُ مُسْلِمٌ بِكَافِرٍ وَلَا ذُو عَهْدٍ فِي عَهْدِهِ إِلَّا مَنْ أَحْدَثَ حَدَثًا أَوْ آوَى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ
