It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: I have been commanded to fight against the people until they say LAA ILAAHA ILLALLAH (there is no god but Allah). So when they say this word, they will protect their lives and their wealth from me, except by its right, and their reckoning is with Allah the Exalted. Then the Prophet (peace and blessings be upon him) recited these verses: {فَذَکِّرْ إِنَّمَا أَنْتَ مُذَکِّرٌ لَسْتَ عَلَیْھِمْ بِمُسَیْطِرٍ} … So remind, you are only a reminder. You are not a controller over them.
