They will do worship Me (alone) and not associate aught with Me; and whoever disbelieves after this, then these are they that are evil-doers." Occasion of Revelation: Many commentators, including Suyuti in Asbab-ul-nuzul, Tabarsi in Majma'-ul-Bayan, Sayyid Qutb in Fi-Zilal, and QurtAbi in his commentary, upon the occasion of revelation of this verse have said: When the Prophet (p.b.u.h.) and Muslims migrated to Medina and were warmly welcomed by Ansar (Helpers), all Arabs became their enemy and it was such that they were to carry a weapon when they went to bed and to be on the alert all the time.
The continuation of this state became difficult for the Muslims. Some of them declared their feeling explicitly: "To what day would this state continue? Would a time come that we could rest calmly in the night and peace and tranquility rule over us and we fear no one but Allahu" The above verse was sent down and gave them this good tiding that of course such a day would come.[^1] Commentary: Islam is a universal religion.
In future victory belongs to the believers and pagans are doomed to be defeated. The key of achieving the Truth and authority of the world is 'Faith' and 'good deeds'. Those who believe and do good deeds glad tidings of victory are given to, not to those who are barely believers. Religion is not separated from politics, but politics and government are for saving religion.
