Learning about Kufr is an essential part of a Muslim’s knowledge about his faith. Without knowing Kufr, you cannot do justice to Tawheed. Kufr is used in the Glorious Quran for people who cover up or hide the truth. It also uses this word to point out those who denied the favours of Allah by not accepting His Dominion and Authority. Therefore Kufr is the opposite of Imaan or Disbelief in Allah and a Non-Believer is called Kaafir.
إِنَّا أَنذَرْنَاكُمْ عَذَابًا قَرِيبًا يَوْمَ يَنظُرُ الْمَرْءُ مَا قَدَّمَتْ يَدَاهُ وَيَقُولُ الْكَافِرُ يَا لَيْتَنِي كُنتُ تُرَابًا
“Indeed We [We] have warned you (of) a punishment near (the) Day will see the man what has sent forth his hands and will say the disbeliever, “O I wish! I were dust!” (Surah An-Naba` 78:40)
The Quran uses the word kufr to denote people who cover up or hide realities. The Qur’an uses this word to identify those who denied Allah’s favours by not accepting His Dominion and Authority. Kufr thus is an antonym for iman or disbelief in Allah and a kafir is a non-believer. This type of kufr is called al-kufr al-Akbar or major kufr. There are many types of al-kufr al-Akbar:
أَلْقِيَا فِي جَهَنَّمَ كُلَّ كَفَّارٍ عَنِيدٍ
“Throw in (to) Hell every disbeliever stubborn.” (Surah Qaf 50:24)
Types of 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 both heart and tongue. Allaah subhanahu wa ta’ala says: They recognize the favours 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 type of kufr applies to those who call 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 boundaries 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 Allah, 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:
Allah Almighty says in the Holy Quran:
ذَٰلِكُمْ فَذُوقُوهُ وَأَنَّ لِلْكَافِرِينَ عَذَابَ النَّارِ
“That – “So taste it.” And that, for the disbelievers (is the) punishment (of) the Fire.” (Surah Al-Anfal 8:14)
وَقَالَ نُوحٌ رَّبِّ لَا تَذَرْ عَلَى الْأَرْضِ مِنَ الْكَافِرِينَ دَيَّارًا
“And said Nuh, “My Lord! (Do) not leave on the earth any (of) the disbelievers (as) an inhabitant.” (Surah Nuh 71:26)
فَاصْبِرْ لِحُكْمِ رَبِّكَ وَلَا تُطِعْ مِنْهُمْ آثِمًا أَوْ كَفُورًا
“So be patient for (the) Command (of) your Lord and (do) not obey from them any sinner or disbeliever.” (Surah Al-Insan 76:24)
وَيَعْبُدُونَ مِن دُونِ اللَّهِ مَا لَا يَنفَعُهُمْ وَلَا يَضُرُّهُمْ وَكَانَ الْكَافِرُ عَلَىٰ رَبِّهِ ظَهِيرًا
“But they worship besides Allah what not profits them and not harms them, and is the disbeliever against his Lord a helper.” (Surah Al-Furqan 25:55)
(a) Rejection of Allaah’s law (Sharee’ah) without denying it
(b) Denial of Allah’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 to invent a lie against Allaah. Verily, those who invent a lie against Allah will never prosper. [Soorah Nahl (16), Ayah 116]
