10:19Mankind was a single community; then they differed. Were it not for a prior decree from your Lord, the matters over which they had disputed would have been settled.

10:38Or do they say, “He has forged it”? Say, “Then produce a single chapter like it, and call upon whomever you can, apart from God, if you are truthful.”
