Losers indeed are those who deny that they will ever face Allah, until when the Hour will come upon them suddenly, they will say, “Alas! We have been negligent about it.” They shall carry their burdens on their backs. Beware! Evil is the burden they carry.
Indeed, many messengers have been rejected before you, but they stood patient against their rejection, and they were persecuted until Our help came to them. No one can change the words of Allah, and of course, some accounts of the messengers have already come to you.
If their aversion is too hard on you, then seek, if you can, a tunnel into the earth or a ladder unto the sky in order to bring them a sign. Had Allah so willed, He would have brought all of them to the right path. So, never be one of the ignorant.
