definition of Kafir in Islam

'Kafir' is an Arabic word that comes from the root K-F-R,

which means to 'cover' something.

The implied meaning is that a kafir sees the truth of Islam,

but still 'covers' it.

Moreover, kafirs are seen as the sworn enemies of Islam and Muslims.

and admits to knowing it with his tongue, but refuses to accept it and refrains from making a declaration.

Muslim Relation

Allah does not forbid you to deal justly and kindly with those who fought not against you

on account of religion nor drove you out of your homes.

Verily, Allah loves those who deal with equity.

(quran Translation 60:8)

O you who believe! Stand out firmly for Allah as just witnesses;

and let not the enmity and hatred of others make you avoid justice.

Be just: that is nearer to piety; and fear Allah.

Verily, Allah is Well-Acquainted with what you do. (quran Translation 5:8)

O you who believe! Stand out firmly for justice, as witnesses to Allah,

even though it be against yourselves, or your parents, or your kin, be he rich or poor,

Allah is a Better Protector to both (than you).

So follow not the lusts (of your hearts), lest you avoid justice;

and if you distort your witness or refuse to give it, verily,

Allah is Ever Well-Acquainted with what you do. . (quran Translation 4:135)
