Those who approach the Book with an open mind are the ones who achieve Guidance from their Sustainer and walk on the right track ((23:1-11), (56:79)). To them belongs the Ultimate Success. (31:2-5)
It is they who follow the guidance from their Lord, and it is they alone who are successful in attaining their object in this life and in the Hereafter
They are in a state of HUDA (comprehension of the reality) from their Rabb (the Name composition comprising their essence) and it is they who are successful.
Sayyed Abbas Sadr-Ameli
