Halal Becomes Impermissible If Certainly It Will Cause Unintentional Sin?
Everything can lead to a haram thing. This is the test. One needs to avoid the haram result from a halal thing. If he commits a haram act the sin will be one of the haram act. If he is sure he cannot avoid a haram act he may choose not to adopt a halal thing. But he will be sinful one when he commits a haram act and will be sinful only for that act.
