In Islam, the munafiqun or falsemuslim were a group decried in the Quran as outward Muslims who were inwardly concealing disbelief and actively sought to undermine the Muslim community. Munafiq is a person who in public and in community shows that he is a Muslim but rejects Islam or propagate against it either in his heart or among enemies of Islam. The hypocrisy itself is called nifāq.
Types of hypocrisy
Hypocrisy towards God regarding actual faith. and
Hypocrisy towards the tenets of faith: for example, somebody may believe in God, Judgment Day, accounting, scales of deeds and Hellfire but not fear them at all or not refrain from committing sins because of them. Yet he claims, "I fear God."
Hypocrisy towards others: somebody is double-faced and double-tongued. He praises someone in their presence, then, behind their back, he denounces them and tries to cause them pain and harm them."
The Qur'an has many verses discussing munāfiqūn, referring to them as more dangerous to Muslims than the worst non-Muslim enemies of Islam.
