the believers may not take the unbelievers for their allies in preference to those who believe. whoever does this has nothing to do with allah unless he does so in order to protect himself from their wrongdoing. allah warns you to beware of him for it is to allah that you will return.
لا يتخذ المؤمنون الكافرين أولياء من دون المؤمنين ومن يفعل ذلك فليس من الله في شيء إلا أن تتقوا منهم تقاة ويحذركم الله نفسه وإلى الله المصير
