It was narrated from ‘Ali (رضي الله عنه) that a man asked him:
Can I recite Qur`an when bowing and prostrating? `Ali (رضي الله عنه) said: The Messenger of Allah (ﷺ) said: “I have been forbidden to recite Qur`an when bowing and prostrating. When you bow, then proclaim the might of Allah, and when you prostrate, offer supplication, for it is more likely that you will receive an answer.”
