13/Ar-Ra'd-43: And those who disbelieve say: “You have not been sent as a Messenger”. Say: “Sufficient as a Witness between me and you is Allah and those too who have the knowledge of the Book.”
14/Ibrahim-1: Alif-Lâm-Râ. (This is) the Book which We have sent down to you that you may bring forth the mankind from utter darkness into the glorious light by their Lord’s Permission - to the Path of the All-Mighty, the Praiseworthy.
14/Ibrahim-2: It is Allah; whose is whatever in the heavens and whatever in the earth. Woe to the disbelievers from a severe torment.
14/Ibrahim-3: They prefer this world’s life to the life of the Hereafter and hinder (others) from the Way of Allah. And they seek to make it crooked; these are in a remote Misguidance.
14/Ibrahim-4: And We did not send any Messenger but with the language of his people, so that he might explain to them clearly (by their own language). Therefore Allah leaves in Misguidance whom He wills (those who do not wish to reach Him) and He delivers whom He wills to Hidayet (Guidance) (those who wish to reach Him). And He is the All-Mighty, the All-Wise.
14/Ibrahim-5: And certainly We sent Moses with Our Verses (proofs, miracles) (saying): “Bring forth your people from utter darkness into the glorious light and remind them of the days of Allah (have them remember the name of Allah during the days of Allah)”. Most surely there are Signs (proofs) in this for the patient, grateful ones.
