باب الْأَمْرِ بِقِتَالِ النَّاسِ حَتَّى يَقُولُوا لَا إِلَهَ إِلَّا اللَّهُ مُحَمَّدٌ رَسُولُ اللَّهِ وَيُقِيمُوا الصَّلَاةَ وَيُؤْتُوا الزَّكَاةَ وَيُؤْمِنُوا بِجَمِيعِ مَا جَاءَ بِهِ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَنَّ مَنْ فَعَلَ ذَلِكَ عَصَمَ نَفْسَهُ وَمَالَهُ إِلَّا بِحَقِّهَا وَوُكِّلَتْ سَرِيرَتُهُ إِلَى اللَّهِ تَعَالَى وَقِتَالِ مَنْ مَنَعَ الزَّكَاةَ أَوْ غَيْرَهَا مِنْ حُقُوقِ الْإِسْلَامِ وَاهْتِمَامِ الْإِمَامِ بِشَعَائِرِ الْإِسْلَامِ
Chapter: The command to fight the people until they say "La ilaha illallah Muhammad Rasul-Allah", and establish Salat, and pay the Zakat, and believe in everything that the prophet (saws) brought. Whoever does that, his life and his wealth are protected except by its right, and his secrets are entrusted to Allah, the most high. Fighting those who withhold Zakat or other than that is one of the duties of Islam and the Imam should be concerned with the Laws of Islam

وحَدَّثَنِي أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا وَكِيعٌ . ح وحَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ يَعْنِي ابْنَ مَهْدِيٍّ ، قَالَا جَمِيعًا : حَدَّثَنَا سُفْيَانُ ، عَنْ أَبِي الزُّبَيْرِ ، عَنْ جَابِرٍ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " أُمِرْتُ أَنْ أُقَاتِلَ النَّاسَ ، حَتَّى يَقُولُوا : لَا إِلَهَ إِلَّا اللَّهُ ، فَإِذَا قَالُوا : لَا إِلَهَ إِلَّا اللَّهُ ، عَصَمُوا مِنِّي ، دِمَاءَهُمْ ، وَأَمْوَالَهُمْ إِلَّا بِحَقِّهَا ، وَحِسَابُهُمْ عَلَى اللَّهِ " ، ثُمَّ قَرَأَ إِنَّمَا أَنْتَ مُذَكِّرٌ { 21 } لَسْتَ عَلَيْهِمْ بِمُسَيْطِرٍ { 22 } سورة الغاشية آية 21-22 .
It is narrated on the authority of Jabir that the Messenger of Allah said: I have been commanded that I should fight against people till they declare that there is no god but Allah, and when they profess it that there is no god but Allah, their blood and riches are guaranteed protection on my behalf except where it is justified by law, and their affairs rest with Allah, and then he (the Holy Prophet) recited (this verse of the Holy Qur'an):" Thou art not over them a warden" (lxxxviii, 22).
