It has been narrated on the authority of Abdullah b. 'Umar that the Messenger of Allah said:
I have been commanded to fight against people till they testify that there is no god but Allah, that Muhammad is the messenger of Allah, and they establish prayer, and pay Zakat and if they do it, their blood and property are guaranteed protection on my behalf except when justified by law, and their affairs rest with Allah.
It Is narrated on the authority of Abu Malik:
I heard the Messenger of Allah ( صلی اللہ علیہ وسلم ) say: He who professed that there is no god but Allah and made a denial of everything which the people worship beside Allah, his property and blood became inviolable, an their affairs rest with Allah.
