Hijrah and the Islamic State
In Surah Nisaa, Allah says:
Translation: They desire that you should disbelieve as they have disbelieved, so that you might be (all) alike; therefore take not from among them friends until they forsake (their homes) in Allah’s way; but if they turn back, then seize them and kill them wherever you find them, and take not from among them a friend or a helper (Surah Nisaa, 4:89)1
