Sunan an-Nasa'i 5003
It was narrated from Anas bin Malik that:
The Messenger of Allah [SAW] said: "I have been commanded to fight the people until they bear witness that there is none worthy of worship except Allah and that Muhammad is the Messenger of Allah. If they bear witness that there is none worthy of worship except Allah and that Muhammad is the Messenger of Allah, they turn to face the same Qiblah as us, they eat our slaughtered animals, and they pray as we pray; then their blood and their wealth are forbidden to us, except for a right that is due, and they have the same rights and duties as the Muslims."
أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمِ بْنِ نُعَيْمٍ، قَالَ أَنْبَأَنَا حِبَّانُ، قَالَ أَنْبَأَنَا 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 ‏"‏ ‏.‏
