REASON WHY GOD ALLOWED FABRICATIONS (Hadith/Sunnah for Muslims, Trinity for Christians; and Mishnah/Gemarrah for the Jews);
[6:113] This is to let the minds of those who do not believe in the Hereafter listen to such fabrications, and accept them, and thus expose their real convictions.
An elaborate trap! a practical joke. Create three or four false religions, THEN create the real one. hehe. God is an Evil Clown.
