Q 7: Is it permissible to perform Ruku‘ (bowing) to one’s parents?
This is impermissible and is tantamount to Shirk (associating others with Allah in His Divinity or worship).
Ruku‘ is a form of worship, just like Sujud (prostration); therefore, it is impermissible to bow or prostrate before anyone other than Allah the Exalted.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
