Well, Allah(swt) guides whom he wills!
For those who says "why have you devided the christians sects but not the islamic ones?":
Answer: shia's and sunni's aren't that much devided, but christians are.. some worship jesus, others dont, some worship mary, others dont, so they have diffrent Gods.. thats diffrent religions.. but shia's and sunnis worship ONE GOD = ALLAH
We follow the same book.. we just differ a little bit on the hadiths! Peacccee out
