Surah Al-Anaam Ayahs #12 Translated in English

And they say, "Why was there not sent down to him an angel?" But if We had sent down an angel, the matter would have been decided; then they would not be reprieved.

And if We had made him [i.e., the messenger] an angel, We would have made him [appear as] a man, and We would have covered them with that in which they cover themselves [i.e., confusion and doubt].

And already were messengers ridiculed before you, but those who mocked them were enveloped by that which they used to ridicule.

Say, "Travel through the land; then observe how was the end of the deniers."

Say, "To whom belongs whatever is in the heavens and earth?" Say, "To Allāh." He has decreed upon Himself mercy. He will surely assemble you for the Day of Resurrection, about which there is no doubt. Those who will lose themselves [that Day] do not believe.
