I’m pretty sure its halal fiqh-wise, but spiritually/akhlaq-wise is my real inquiry

In regards to singing of (not ghina type) Christian-authored songs with the niyyah of dhikr, magnifying God, and lifting ones mood, perhaps better / safer to turn the Qur’an Pak instead?

If the wording are just praising Allah s.w.t. and no negative thing as per our ideology then one can sing or listen but no doubt Quran is the message of Allah all mercy ever mercy it has much more deep effect on souls and minds
