Quran 3:28
"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."
Quran 3:54
"And when the disbelievers plotted against them, we plotted, and we plotted against them unbeknownst to them."
