Miserable indeed is for which they sell their 'Selves' - that they deny that which Allah has revealed. (Grudgingly, they cannot get over the fact that Allah has chosen a Messenger who is not an Israelite). And that Allah should reveal His bounty to whomever He chooses among His servants. And so (for their discriminatory attitude) they have invited Requital upon Requital. And for all those who thanklessly deny the Guidance and choose to live in darkness, is a logical consequence of suffering that brings them low.
