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 (ﷺ) 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 Iman should be concerned with the Laws of Islam
Abu Huraira reported the Messenger of Allah (ﷺ) as saying:
When Satan hears the call to prayer, he turns back and breaks the wind so as not to hear the call being made, but when the call is finished he turns round and distracts (the minds of those who pray), and when he hears the Iqama, he again runs away so as not to hear its voice and when it subsides, he comes back and distracts (the minds of those who stand for prayer).
