Shia Muslims take the Tafseer of Quran from the Prophet (S.A.W.A) through the most authentic source who are Ahlulbayt (A.S). We don't take the opinions of people even the famous scholars in understanding Quran, unless it has been taken from the Authentic Hadeeth of Prophet (S.A.W.S) and his Ahlulbayt (A.S).
We believe in Bila Kayf بلا كيف regarding the attributes of Allah as human mind is limited and it cannot reach to the unlimited attributes of Allah.
Wasalaam
