Hadith on Aggression: The Prophet’s sword condemns unjust killing

Aisha reported: I found an engraving on the sword of the Messenger of Allah, peace and blessings be upon him, that wrote, “Verily, the worst of people in insolence are those who strike at whoever did not strike them, a man who kills those who did not fight him, and a man who claims allegiance to those other than his rightful benefactors. Whoever does so has disbelieved in Allah and his messenger. Allah will not accept his obligatory or voluntary deeds.”

عَنْ عَائِشَةَ قَالَتْ وَجَدْتُ فِي قَائِمِ سَيْفِ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ كِتَابًا إِنَّ أَشَدَّ النَّاسِ عُتُوًّا مَنْ ضَرَبَ غَيْرَ ضَارِبِهِ وَرَجُلٌ قَتَلَ غَيْرَ قَاتِلِهِ وَرَجُلٌ تَوَلَّى غَيْرَ أَهْلِ نِعْمَتِهِ فَمَنْ فَعَلَ ذَلِكَ فَقَدْ كَفَرَ بِاللَّهِ وَرَسُولِهِ لَا يَقْبَلُ اللَّهُ مِنْهُ صَرْفًا وَلَا عَدْلًا
