Couple of days back I was in a discussion of TAQLEED with some people, where there were pro-Taqleed and anti-Taqleed parties. Over there one of the person was strictly against titles i.e Ayatullah Hujjatullah and Imam being taken by Marajs and Scholars. That person was of a view that these TITLES only belongs to Masooms and nobody has the right to use these TITLE for them.
Can someone please elaborate Why these titles are been taken my non-masooms scholars. Most importantly in what context IMAM is used by Supreme leader of IRAN and Does anyone has the right to take this title IMAM a part from our IMAMS opted by Allah.
