Holy Quran » AN NISAA' : 116

Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly gone far astray.

{ إن الله لا يغفر أن يُشرك به ويغفر مادون ذلك لمن يشاء ومن يشرك بالله فقد ضل ضلالا بعيدا } عن الحق .
