And indeed We have already sent (Our) Messengers before you. There are some of them whom We have mentioned to you and of them there are some whom We have not mentioned to you. And it is not given to a Messenger to bring a Message by himself except by the leave of Allâh. But when the judgment of Allâh comes to pass the issues are settled in all fairness, and it is then that who endeavour to nullify the truth suffer the loss.
