Whoever maintains friendship with Allah and His Messenger and those who believe (must know that) it is the (members of the) Party of Allah that are the triumphant.
O you who believe, do not take those who have taken your Faith in jest and fun for friends from those who have been given the Book prior to you, and the disbelievers. Fear Allah, if you are believers.
Say, “O People of the Book, do you accuse us of anything else except that we have believed in Allah and in what has been sent down to us and what has been sent down earlier while most of you are sinners (and we do not follow you in your sins)
Say, “Shall I tell you about the ones whose retribution with Allah is worse than that (which you deem bad)? They are those whom Allah has subjected to His curse and to His wrath; and He has turned some of them into apes and swine, those who worshipped Tāghūt (Satan, the Rebel). Those are worse in their situation, and far more astray from the straight path.”
When they come to you, they say, “We believe”, while with disbelief they came in, and with the same (disbelief) they went out. Allah knows best what they used to conceal.
