It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: I have been commanded to fight the people until they say La ilaha illallah (there is no god but Allah). When they say the kalimah, they have protected their lives and wealth from me, except for the right of this kalimah, and their reckoning is with Allah.
