28th Ayah from Surah Al 'Imran

Let not believers take disbelievers as allies rather than believers. And whoever [of you] does that has nothing with Allah, except when taking precaution against them in prudence. And Allah warns you of Himself, and to Allah is the [final] destination.
Abdul Haleem
The believers should not make the disbelievers their allies rather than other believers- anyone who does such a thing will isolate himself completely from God- except when you need to protect yourselves from them. God warns you to beware of Him: the Final Return is to God.
Mohsin Khan/Hilali
Let not the believers take the disbelievers as Auliya (supporters, helpers, etc.) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His Punishment), and to Allah is the final return.
Taqi Usmani

Pickthall
Let not the believers take disbelievers for their friends in preference to believers. Whoso doeth that hath no connection with Allah unless (it be) that ye but guard yourselves against them, taking (as it were) security. Allah biddeth you beware (only) of Himself. Unto Allah is the journeying.
Pickthall
