If someone wanted to have Faith like Salman Al-Farisi, what did Prophet Muhammad (saw) say would be necessary?
 Narrated Abu Huraira:                     While we were sitting with the Prophet Surat Al-Jumu'a was revealed to him, and when the Verse, "And He (Allah) has sent him (Muhammad) also to other (Muslims).....' (62.3) was recited by the Prophet, I said, "Who are they, O Allah's Apostle?" The Prophet did not reply till I repeated my question thrice. At that time, Salman Al-Farisi was with us. So Allah's Apostle put his hand on Salman, saying, "If Faith were at (the place of) Ath-Thuraiya (pleiades, the highest star), even then (some men or man from these people (i.e. Salman's folk) would attain it."
