“They desire to put out the light of God with their mouths...
“They desire to put out the light of God with their mouths, but God will perfect His light, though the disbelievers may be averse.” 9:32; 61:8 “He is the One Who sent His Messenger with the guidance and the true religion, to make it outweigh all other religions though the polytheists may be averse.” 9:33; 61:9 and 48:28. The first verse predicts that the opponents of Islam will not succeed in putting out the light of God, nor will their attacks hinder its growth.
God will make His light, Islam, perfect, though its opponents will oppose it strongly. They may argue, fight, assail and mobilize all their intellectual and material forces, determining to revoke Islam, but all that will not extinguish its light, nor will that prevent it from becoming full. Both verses predict definitely and unconditionally the victory of Islam over its opponents.
When this prophecy was revealed, the small Muslim community was defending itself against the Polytheists and other hostile elements in Arabia. Afterwards it had to defend itself against the Persian and Byzantine Empires. Each of these powers was incomparably greater and richer than the Muslim state. The Persian and Byzantine Empires were the outstanding forces in the world. To defeat them both is to defeat all considerable forces in the world and to become the world's superior power.
This would fulfill completely the meaning of the prophecy, but this was seemingly impossible. We always expect the defeat of any single and relatively weak army when forced to combat on more than one field more than one superior power. This becomes clear when we remember that the mighty German army had been defeated twice in the twentieth century, only because it was fought by stronger allies on more than one front.
It may be the most remarkable military event in history, that the inhabitants of Madina and Mecca, whose number did not exceed a few thousands, could defend themselves, after the death of the great Prophet, against the attacks of the apostate Arabs. With the exception of the Muslims of these two cities, almost all the Arab nation had apostatized after the death of the Prophet. The Muslim state was compelled, afterwards, to fight against the Byzantine and Persian Empires.
These two great empires fought the Muslims simultaneously on two different fronts. The scanty Muslim forces were forced to divide themselves in order to maintain the defense. The result was a wondrous military phenomenon.
