Ibn ‘Umar reported God’s messenger as saying, "I am commanded to fight with men till they testify that there is no god but God and that Muhammad is God's messenger, observe the prayer and pay the <i>zakat</i>. When they do that they will keep their lives and their property safe from me, except for what is due to Islam; and their reckoning will be at God’s hands.” (Bukhari and Muslim, but Muslim did not mention, "except for what is due to Islam”.)

وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ وَيُقِيمُوا الصَّلَاةَ وَيُؤْتُوا الزَّكَاةَ فَإِذَا فَعَلُوا ذَلِكَ عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلَّا بِحَق الْإِسْلَام وحسابهم على الله. إِلَّا أَنَّ مُسْلِمًا لَمْ يَذْكُرْ» إِلَّا بِحَقِّ الْإِسْلَام "
