Professor Hussein Ansarian considered paying attention to narrations beside the verses of the Holy Quran essential and said: we must tell the narrations along with the Holy Quran to people, the Holy Quran is no longer in use if we don't refer to narrations. The Holy Quran has raised the issue of Prayer more than one hundred times, where in these verses it talked about how many Rakats (units) the morning prayers, noon and evening prayers must be? Where in the Holy Quran you can find about the details of saying prayers? All such issues are mentioned by narrations. In fact, the narrations are closely related with the Holy Quran, neither of them can be separately applicable.
