Prominent Hadith
I have been ordered to fight against people until they testify that there is no god but Allah and that Muhammad is the Messenger of Allah and until they perform the Zakat,
And if they do so they will have gained protection from me for their lives and property,
Unless they do acts that are punishable in accordance with Islam
And their reckoning will be with Allah the Almighty.
Hadith 8
