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
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا عَبْدَةُ، عَنْ طَلْحَةَ بْنِ يَحْيَى، عَنْ عَمِّهِ، قَالَ كُنْتُ عِنْدَ مُعَاوِيَةَ بْنِ أَبِي سُفْيَانَ فَجَاءَهُ الْمُؤَذِّنُ يَدْعُوهُ إِلَى الصَّلاَةِ فَقَالَ مُعَاوِيَةُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ الْمُؤَذِّنُونَ أَطْوَلُ النَّاسِ أَعْنَاقًا يَوْمَ الْقِيَامَةِ " وَحَدَّثَنِيهِ إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا أَبُو عَامِرٍ، حَدَّثَنَا سُفْيَانُ، عَنْ طَلْحَةَ بْنِ يَحْيَى، عَنْ عِيسَى بْنِ طَلْحَةَ، قَالَ سَمِعْتُ مُعَاوِيَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِمِثْلِهِ
Yahya narrated it on the authority of his uncle that he had been sitting in the company of Mu'awiya b. Abu Sufyan when the Mu'adhdhin called (Muslims) to prayer. Mu'awiya said:
I heard the Messenger of Allah (ﷺ) saying The Mu'adhdhins will have the longest necks on the Day of Resurrection.
