I think for some they are just reading and practicing religious doctrines because they are told they have to. In the article itself when Israr Ahmed states that people who simply recite their daily prayers without knowing the true meaning behind what they are reciting are doing it to fulfill the 5 daily paryers required of a Muslim. This is not only selfish but they are doing so for the reward they will receive in the long run from God… he reward of the after life or on the Day of Judgment. But people who do this are not taking the true essence of what the Qur’an is teaching. The Holy Book should be used as guidance and direction for lead righteous lives, not for reasons not to be sent to hell. I think Israr Ahmed’s target audience were Muslims and he is trying to convey the idea of not taking the Qur’an for granted, but simply appreciating its teachings and applying them to daily life will bring happiness to them.
You say that there is no purpose of reading and understanding religious scriptures if one does not apply it to daily life, but then you say how difficult it is to apply it. I agree with you on the fact that it is quite difficult to implement religious teachings into our daily lives with all the distractions that surround us. But is one not a true believers if they don’t apply ever aspect of it?
