Q: If I know a Surah of by heart but play a recording of it whilst reading (to make sure I do not make mistakes), will my Tilaawah (e.g. of my night Surahs) be complete?
A: This is incorrect. The tilaawat must be done with focus. You cannot be listening and reciting at the same time. The Qur’aan has a right that you listen to it attentively, and listening to it attentively means that you remain absolutely silent.
And Allah Ta’ala (الله تعالى) knows best.
