It was narrated from Anas bin Malik that :The Messenger of Allah [SAW] said: "I have been commanded to fight the idolators until they bear witness to La ilaha illallah (there is none worthy of worship except Allah) and that Muhammad is the Messenger of Allah [SAW]. If they bear witness to La ilaha illallah and that Muhammad is the Messenger of Allah [SAW], and they face our Qiblah, eat our slaughtered animals, and pray as we do, then their blood and wealth become forbidden except for a right that is due, and they will have the same rights and obligations as the Muslims."
أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمِ بْنِ نُعَيْمٍ، قَالَ أَنْبَأَنَا حِبَّانُ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ حَتَّى يَشْهَدُوا أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ فَإِذَا شَهِدُوا أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ وَاسْتَقْبَلُوا قِبْلَتَنَا وَأَكَلُوا ذَبِيحَتَنَا وَصَلَّوْا صَلاَتَنَا فَقَدْ حَرُمَتْ عَلَيْنَا دِمَاؤُهُمْ وَأَمْوَالُهُمْ إِلاَّ بِحَقِّهَا لَهُمْ مَا لِلْمُسْلِمِينَ وَعَلَيْهِمْ مَا عَلَيْهِمْ " .
