Quran 5.55-57
Your guardian can be only Allah; and His messenger and those who believe, who establish worship and pay the poordue, and bow down (in prayer). And whoso taketh Allah and His messenger and those who believe for guardian (will know that), lo! the party of Allah, they are the victorious. O Ye who believe! Choose not for guardians such of those who received the Scripture before you, and of the disbelievers, as make a jest and sport of your religion. But keep your duty to Allah if ye are true believers.
