Dear Brother ,
Peace be upon you . You answered exactly what in my mind . This is just absolute logic per Quran's perspective .
But still now it is prevailing that many hadith states that only recitation of the Quran without any understanding ( specific sura , verses etc... ) can benefit us for the recover of any crisis we are facing . It is mentioned that recitation of some verses or sura will give you give us Jannah , will not put us into trouble , some of them will make you rich , some of them will benefit us for many obstacles etc......
It is also mentioned if recitation of some specific sura , verses tow times , three times will benefit us . Many Muslims is practicing like this way ....... Some times it is mentioned of some story , event as the proof of the recitation of the partly Quran or it's verses . For Example ... If any one recites a certain sura three times daily he never face poverty ..
I will be glad if any one of this forum can give me strong evidence that no benefit will come to us either in earthly life or in after world only recitation of the Quran without understanding .
Best/Rgds.
