كُفْرٌ
1.
See كَفَرَ الشَّىْءَ.
[As a simple subst., Ingratitude, &c.2.
And particularly Denial, or disacknowledgment, of favours or benefits, and especially of those conferred by God: and disbelief, unbelief; infidelity.] It is of four kinds: كُفْرُ إِنْكَارٍ
the denial, or disacknowledgment, of God, with the heart and the tongue, having no knowledge of what is told one of the unity of God [&c.]: and كُفْرُ جُحُودٍ
the acknowledgment with the heart without confessing with the tongue: [or the disacknowledgment of God with the tongue while the heart acknowledges Him:] and كُفْرُ
المُعَانَدَةِ the knowledge of God with the heart, and confession with the tongue, with refusal to accept [the truth]: and كُفْرُ النِّفَاقِ
the confession with the tongue with disbelief in the heart: all of these are unpardonable: (L, TA:) the greatest كُفْر is the denial, or disacknowledgment, of the unity [of God], or of the prophetic office [of Mohammad and others], or of the law of God. (El-Basáïr.) [Also, Blasphemy. Its plural, as a simple subst. in all these senses, is said to be كُفُورٌ.]. Akh says, that كُفُورًا [in the accusative case] in the Qur'an, 17:101, [to which may be added v. 91 of the same ch., and xxv. 52,] is plural of كُفْرٌ, like as بُرُودٌ is plural of بُرْدٌ. (S.)

Tar, or pitch, synonym قِيرٌ; with which ships are smeared; (K;) of which there are three sorts, كُفْرٌ and قِيرٌ and زِفتٌ: كفر is melted, and then ships are smeared with it: [whence, apparently, its name, from its being a covering:] زفت is used for smearing skins for wine, &c. (ISh.)
