Why did Allah not make His religion the most widespread and dominant so that corruption and disbelief would end and the Day of Judgment would commence with the entire world being Muslim, instead of it returning to being a stranger as it began, even though it is the last message from Allah to mankind?

Allah Almighty created nothing but with wisdom, and all His decree is wisdom. He decreed that Islam would return as something strange, and that people would divide into two parties: the party of the Most Merciful and the party of Satan. Among the wisdoms behind this are the testing of believers and the establishment of Jihad to attain its ranks, as Allah Almighty said: "And if Allah had willed, He could have taken vengeance upon them; but [He ordained it thus] to test some of you by means of others," and His saying: "Do people think that they will be left alone because they say, 'We believe,' and will not be tested?" Thus, wisdom dictates that evil should not be pure, but rather evil may carry within it predominant benefits and wisdoms.
