The most precious treasure that we possess is Imaan. But it should be understood that this most precious treasure is extremely delicate and can be quickly eradicated by thoughtless acts and attitudes. Among such dangerous acts and attitudes which efface this most precious treasure is Istikhfaaf. Istikhfaaf makes light of any tenet, teaching and belief of Islam regardless of the Fiqhi classification. If even a Mustahab act or an act which is of a lesser degree than Mustahab, is dismissed with the attitude of Istikhfaaf, it will be kufr such kufr which effaces Imaan. Hence, the Fuqaha have ruled: Nowadays so much Istikhfaaf is committed with the teachings of the Deen, which leaves no doubt in the effacement of Imaan. Mockery with Hijaab, the beard, Islamic dress, etiquettes of eating, etc., etc. is a clear attitude of Istikhfaaf which eliminates Imaan. When viewing the alarming and widespread attitude of Istikhfaaf This dangerous disease of Istikhfaaf is so endemic nowadays that we find numerous molvis and sheikhs also committing this fatal sin. When a Muslim perpetrates Istikhfaaf with any order or institution of the Shariah, he implies preference for the system of the kuffaar. The disdain which he feels for the Islamic institution constrains him to elevate the kuffaar system and to propagate its superiority and necessity. It is on this basis that Hadhrat Maulana Ashraf Ali Thanvi (rahmatullah alayh) and our Akaabir Ulama issued the fatwa of kufr regarding thekuffaar system of slaughtering animals. The attitude of preference for the kuffaar system and the total abandonment of the Islamic system are the effects of Istikhfaaf which in turn are the products of monetary greed. It is the lust for money which has blinded the bodies which halaalize haraam carrion meat.
