And here are the most important controls for this legal rule: First: It is necessary to know the state of the person committing disbelief. If a Muslim does not know the state of the person committing disbelief, he does not declare him an unbeliever due to his ignorance of his disbelieving act, and thus he is excluded from this rule. Second: The person committing disbelief must have committed an act of disbelief that is agreed upon and not disputed. If he commits a disputed act of disbelief, such as abandoning prayer out of laziness, then a Muslim does not declare him an unbeliever because the one who abandons prayer is not declared an unbeliever, and thus he is excluded from this rule. Third: The person committing disbelief must have committed an act of disbelief that is known from religion by necessity. What is known from religion by necessity is the legal ruling that has become apparent and famous among Muslims, and its ignorance is inconceivable for a scholar or a layperson, or for the elite or the general public. It differs from place to place and from time to time. The diligent scholars of each time and place determine this. If the act of disbelief committed by the person is not known from religion by necessity to be disbelief or that its perpetrator is an unbeliever, then he is not declared an unbeliever. This is like the disbelief of one who rules by other than what Allah has revealed and the ruling of man-made laws. This is an agreed-upon disbelief, but it is not known from religion by necessity in our time, because some general texts and sayings have been confused for many ignorant people and innovators, and they have applied them to the wrong context, and they have misinterpreted the verses and hadiths concerning this matter with corrupt interpretations. Thus, the act, despite being agreed upon as disbelief, is not known from religion by necessity. Therefore, whoever does not declare that person who committed disbelief an unbeliever due to these doubts and corrupt interpretations, is excluded from this rule.
