الفعل للمجهول او المبني للمجهول when the doer of the verb is unknown. It is used for four reasons according to the scholars of the language:
- للعلم- We already know who the doer is. For example, خلق آدم من طين Adam (as) was created from mud.
- للجهل- We don’t know who did the action.
- للخوف- We are scared of the one who did the action, so we don’t mention his name.
- للخوف على الفاعل – He’s not mentioned out of fear of the doer himself.
