Am i wrong at this position on telling him what to do w/o daleel?
Advise should be given with total wisdom and humility. A person advising another person should convince him with his character, then if a person offers a Daleel or not, one should be eveready to practice on his/her advice.
Nevertheless, the manner of reciting the Qur’aan is one of etiquette. It is not something stipulated in Deen. However, maintaining Adaab when reading the Qur’aan is a great virtue. The procedure mentioned by you is not in any Hadith according to our knowledge.
and Allah Ta’ala Knows Best
