'Amr bin Aws told him that his father Aws said: "The Messenger of Allah [SAW] said: 'I have been commanded to fight the people until they bear witness to La ilaha illallah (there is none worthy of worship except Allah), then their blood and their wealth become forbidden to me, except for a right that is due." (Using translation from Nasāʾī 3983)
قَالَ رَسُولُ اللهِ ﷺ «أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أَنْ لَا إِلَهَ إِلَّا اللهُ ثُمَّ تَحْرُمُ دِمَاؤُهُمْ وَأَمْوَالُهُمْ إِلَّا بِحَلِّهَا»
