Sahih al-Bukhari, Hadith 25 ⓘ
Narrated Ibn 'Umar: Allah's Messenger said: "I have been ordered (by Allah) to fight against the people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Messenger, and offer the prayers perfectly and give the obligatory charity, so if they perform that, then they save their lives and property from me except for Islamic laws and then their reckoning (accounts) will be done by Allah."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الْمُسْنَدِيُّ، قَالَ حَدَّثَنَا أَبُو رَوْحٍ الْحَرَمِيُّ بْنُ عُمَارَةَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ وَاقِدِ بْنِ مُحَمَّدٍ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ، وَيُقِيمُوا الصَّلاَةَ، وَيُؤْتُوا الزَّكَاةَ، فَإِذَا فَعَلُوا ذَلِكَ عَصَمُوا مِنِّي دِمَاءَهُمْ وَأَمْوَالَهُمْ إِلاَّ بِحَقِّ الإِسْلاَمِ، وَحِسَابُهُمْ عَلَى اللَّهِ " .
