1. Kufrul-’Inaad: Disbelief out of stubborness. This applies to someone who knows the truth and admits to knowing the truth and admits to knowing it with his tongue, but refuses to accept it and refrains from making a declaration. Allaah subhanahu wa ta’ala says:

Throw into Hell every stubborn disbeliever
[Soorah Qaaf (50), Ayah 24]

2. Kufrul-Inkaar: Disbelief out of denial. This applies to someone who denies with both heart and tongue. Allaah subhanahu wa ta’ala says:

They recognize the favors of Allaah, yet they deny them.
Most of them are disbelievers.
[Soorah Nahl (16), Ayah 83]

3. Kufrul-Kibr: Disbelief out of arrogance and pride. The disbelief by the devils (Iblees) is an example of this type of Kufr.

4. Kufrul-Juhood: Disbelief out of rejection.This applies to someone who aknowledges the truth in his heart, but rejects it with his tongue. This types of kufr is applicable to those who calls themselves Muslims but who reject any necessary and accepted norms of Islam such as Salaat and Zakat. Allaah subhanahu wa ta’ala says:

They denied them (OUR SIGNS) even though
their hearts believed in them,
out of spite and arrogance.
[Soorah Naml (27), Ayah 14]

5. Kufrul-Nifaaq: Disbelief out of hypocrisy.This applies to someone who pretends to be a believer but conceals his disbelief. Such a person is called a MUNAFIQ or hypocrite. Allaah subhanahu wa ta’ala says:

Verily the hypocrites will be in the lowest
depths of Hell.
You will find no one to help them.
[Soorah An Nisaa (4), Ayah 145]

6. Kufrul-Istihaal: Disbelief out of trying to make HARAM into HALAL. This applies to someone who accepts as lawful (Halal) that which Allaah has made unlawful (Haram) like alcohol or adultery.Only Allaah subhanahu wa ta’ala has the prerogative to make things Halal and Haram and those who seek to interfere with His right are like rivals to Him and therefore fall outside the boundries of faith.

7. Kufrul-Kurh: Disbelief out of detesting any of Allaah’s subhanahu wa ta’ala commands. Allaah subhanahu wa ta’ala says:

Perdition (destruction) has been
consigned to those who disbelieve and
He will render their actions void.
This is because they are averse to that which
Allaah has revealed so He has made their actions fruitless.
[Soorah Muhammed (47), Ayah 8-9]

8. Kufrul-Istihzaha: Disbelief due to mockery and derision. Allaah subhanahu wa ta’ala says:

Say: Was it at Allaah,
His signs and His apostles that you were mocking?
Make no excuses. You have disbelieved after
you have believed.
[Soorah Taubah (9), ayah 65-66]

9. Kufrul-I’raadh: Disbelief due to avoidance. This applies to those who turn away and avoid the truth. Allaah subhanahu wa ta’ala says:

And who is more unjust than he who is reminded
of his Lord’s signs but then turns away from them.
Then he forgets what he has sent forward
(for the Day of Judgement)
[Soorah Kahf (18 ), Ayah 57]

10. Kufrul-Istibdaal: Disbelief because of trying to substitute Allaah’s Laws. This could take the form of:

(a) Rejection of Allaah’s law (Sharee’ah) without denying it
(b) Denial of Allaah’s law and therefore rejecting it, or
(c) Substituting Allaah’s laws with man-made laws. Allaah subhanahu wa ta’ala says:

Or have they partners with Allaah
who have instituted for them a religion
which Allaah has not allowed.
[Soorah Shuraa(42), Ayah 8]

Allaah subhanahu wa ta’ala says:

Say not concerning that which
your tongues put forth falsely (that)
is lawful and this is forbidden so as
to invent a lie against Allaah.
Verily, those who invent a lie against
Allaah will never prosper.
[Soorah Nahl (16), Ayah 116]
