Dissent, heresy and freethought
Definition
Ilhad in the lexical sense is deviation and turning away from a thing; the grave niche (lahd) takes its name from it. In usage it has several senses. The first is ilhad in religion: attacking it or leaving it. The second is violating the sanctity of the Sacred Mosque by sin there or by preventing its maintenance. 1 Ibn Abidin said that ilhad in religion is turning from the sound law toward some form of unbelief, such as the Batiniyya who claim that the Qur'an has an outer and an inner sense, and that it includes attacking the religion while claiming to be a Muslim, or twisting the necessities of the religion to suit one's desires. 1

Ilhad in the Sacred Precinct
Ilhad in the Sacred Precinct is deviation through injustice there, as the Qur'an says of its sanctity. The sayings on its meaning differ: Ibn Mas'ud took it as polytheism; others as violating its sanctity by injustice, doing wrong, preventing its maintenance, or hoarding. Ibn Hayyan held that these are examples and not a closed list. 3

Ilhad in religion and its effects
- The one who commits ilhad may be a polytheist by origin, whose case falls under polytheism; a dhimmi who attacks the religion openly, whose covenant is then broken; or a Muslim, who takes the rulings of apostasy or heresy. 4
- A Muslim who turns to ilhad is asked to repent by those who hold that view. If he repents he regains his acts of worship and his contracts; if he does not, he is treated as an executed apostate. 4
