Answer:
To make Ruku (bow down) or to make Sujood (to prostrate), both are only for Allah. Allah Ta’ala says in Surah Hajj, ?Oh you who believer, make Ruku and Sujood and worship your Rabb and do good so that you may prosper.?
It is prohibited to bow down or prostrate for any human being.
and Allah Ta’ala Knows Best
