Allah 's Apostle said, " I have been ordered to fight with the people till they say, 'None has the right to be worshipped but Allah,' and whoever says, 'None has the right to be worshipped but Allah,' his life and property will be saved by me except for Islamic law, and his accounts will be with Allah, (either to punish him or to forgive him.)"
أَخْبَرَنَا أَحْمَدُ بْنُ مُحَمَّدٍ قَالَ حَدَّثَنَا عُثْمَانُ عَنْ شُعَيْبٍ وَأَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ بْنِ سَعِيدِ بْنِ كَثِيرٍ قَالَ حَدَّثَنَا أَبِي قَالَ حَدَّثَنَا شُعَيْبٌ عَنِ الزُّهْرِيِّ قَالَ حَدَّثَنِي سَعِيدُ بْنُ الْمُسَيِّبِ أَنَّ أَبَا هُرَيْرَةَ
أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ «أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَقُولُوا لَا إِلَهَ إِلَّا اللهُ فَمَنْ قَالَهَا فَقَدْ عَصَمَ مِنِّي نَفْسَهُ وَمَالَهُ إِلَّا بِحَقِّهِ وَحِسَابُهُ عَلَى اللهِ»
