Nu’man bin Sa’d says that a man asked Sayyiduna Ali (may Allah be pleased with him),“Can I recite (Qur’an) during bowing (ruku’) and prostration (sujud)?”He replied: The Messenger of Allah (peace and blessings be upon him) said:“I have been forbidden from reciting the Qur’an while in the state of bowing and prostration. When you bow, then glorify the greatness of Allah, and when you prostrate, then make supplication with full attention, for it is likely that your supplication will be answered.”
