Was Prophet Yusuf (as) the leader of Prophet Jacob (as) during their lifetime rather than the other way around? If so, what was the reason?
Prophet Yusuf (AS) was son of Prophet Jacob (AS). Prophet Yusuf became the leader of the country of Egypt when his father was not the leader of the country. The leadership of Yusuf over the country made his parents and brothers deal with him according to the norms of the country and society but that is a different matter from the status of the prophet hood.
