I would like to know regarding the Stages of Iman in reference to a narration I heard that said Hz. Salman Farsi was on the 10th stage of the Iman while Hz. Aba Dharr was on the ninth. I would also like to know if a sinner like myself can atleast try to acheive those stages or acheive the level of irfan and if yes then what are the early steps that need to be taken in order to purify one's soul for the purpose of achieving higher stations in the eyes of Ahlulbait (as)?

Well it's not easy to understand that stages neither required because we have to uplift our Emaan. Irfan needs teacher that can help to gain ranks and understand world so it's a procedure and continuous struggle.
