From Enmity to Friendship, Except When…
Imām Ibn Taimiyyah, may Allāh have mercy on him, said: “From the well-known verses [in support of not putting non-Muslims in positions of trust or influence over Muslims in Muslim lands] is the saying of one of them:
كُلُّ العَدَاوَاتِ [قَدْ] تُرْجَى مَوَدَّتُهَا
إِلاَّ عَدَاوَةَ مَنْ عَادَاكَ فِي الدِّينِThere’s hope for friendship in all animosities
Except animosity from those opposed to you for the religion.
