Interesting. Could you elaborate on what you mean by 'practical teachings from the quran'?
It is about ignoring the mutasyaabihat (3.7). . . Allah, hell, paradise, satan and all the allegorical are the nonsense. . . The nonsense in the Quran is for the hypocrites and the disbelievers (74.31). It is the system of Allah to help Believers identify the hypocrites in their community.
On the other hand, True Muslim has "no doubt", "fear" or "grievances" because they are "certain about life" and don't entertain the nonsense. The true Muslim focuses on the "Deen", ie. practical Muslim living, and not living in the illusion of the past or future, but "present"

. They follow what is entirely clear and provable from the Quran, and leave which cannot be proven through facts.
