As we know being a mujtahid, you are required to be born from a halal consummated marriage, now why is that a ruling as what takes away from one’s who were born by their parents sin and aren’t we not supposed to differentiate between muslims? After all they are only collecting the narrations of our prophet and imams and deriving us fatwas. May I know what’s the reason to that being a rule of being a mujtahid? And may I know a narration from the Imams that proves this concept too inshallah?
