BismilLaahir Rahmaanir Raheem.
The Qur’aan uses the word Kufr to denote people who cover up or hide realities. The Qur’an uses this word to identify those who denied Allaah’s favors by not accepting His Dominion and Authority. Kufr thus is an antonym for Eeman or disbelief in Allaah and a Kaafir is a non-believer. This type of Kufr is called AL-KUFR UL AKBAR or major kufr. There are many types of Al-Kufr ul Akbar:
1. Kufrul-‘Inaad: Disbelief out of stubbornness. 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 acknowledges 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]. To be continued in shaa Allah.
May Allah protect us from any type of kufr. Aameen.
