Sufyan ibne Abdullah Aththaqafi Radiyallahu anhu narrated
that I asked: O Rasulallah! (Sall Allahu alaihi wa Aalihi wa Sallim)
Tell me something most important about Islam, so that I will
have no further need to ask about this from anyone after you.
He (Sall Allahu alaihi wa Aalihi wa Sallim) said:
Say, I believe in Allah, and be steadfast therein.
(Muslim)
