O believers! Do not associate closely with others who would not miss a chance to harm you. Their only desire is to see you suffer. Their prejudice has become evident from what they say—and what their hearts hide is far worse. We have made Our revelations clear to you, if only you understood.
— Dr. Mustafa Khattab, the Clear Quran
O you who have believed, do not take as intimates those other than yourselves [i.e., believers], for they will not spare you [any] ruin. They wish you would have hardship. Hatred has already appeared from their mouths, and what their breasts conceal is greater. We have certainly made clear to you the signs, if you will use reason.
