If they were to get the better of you, they would behave to you as enemies, and stretch forth their hands and their tongues against you for evil: and they desire that ye should reject the Truth. Al-Mumtahanah 60:2 ⧉
Tafsir:
During the state of war, when the position is that Islam and non-Islam have become polarised on separate fronts, it is the responsibility of the people of Islam to sever their relations with the non-Islamic front, even if their relatives and dear ones are part of it. Being a believer in Truth and at the same time having close relations with the enemies with whom one is at war is totally wrong.
