ISLAMIC OBLIGATIONS H 1232 "I have been commanded to continue fighting until people bear witness that there is no god except Allah and that Muhammad is His Messenger, to offer the daily prayers and to pay the obligatory charity. Once they have accepted this their lives and property will be safe from me, and they have become subject to their Islamic obligations being accountable to Allah." R 1232 Bukhari and Muslim with a chain up to ibn Omar who related that the Messenger of Allah, praise and peace be upon him, said this.
1209- وعن ابن عمر رضي الله عنهما ، قَالَ : قَالَ رسولُ الله صلى الله عليه وآله وسلم : "أُمِرْتُ أنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أنْ لاَ إلهَ إِلاَّ اللهُ، وَأنَّ مُحَمَّداً رسول الله ، وَيُقِيمُوا الصَّلاةَ ، وَيُؤتُوا الزَّكَاةَ، فَإذَا فَعَلُوا ذَلِكَ عَصَمُوا مِني دِمَاءهُمْ وَأمْوَالَهُمْ ، إِلاَّ بِحَقِّ الإسْلاَمِ ، وَحِسَابُهُم عَلَى الله" متفقٌ عَلَيْهِ .
