And if their turning away is hard on you, then if you can seek an opening (to go down) into the earth or a ladder (to ascend up) to heaven so that you should bring them a sign and if Allah had pleased He would certainly have gathered them all on guidance, therefore be not of the ignorant.

Surely (as for) those who reject Our communications and turn away from them haughtily, the doors of heaven shall not be opened for them, nor shall they enter the garden until the camel pass through the eye of the needle; and thus do We reward the guilty.
