Big Question: Do we realy need to do Sajdah other than Allah? Did Prophet Mohammad (PBUH) tell us to do this?

please read the hadith given below that how prophet Muhammad (PBUH) forbade his companion who bowed with respect..
it is narrated that when Mu-aadh ibn Jabal (may Allaah be pleased with him) came back from Syria he prostrated to the Prophet (peace and blessings of Allaah be upon him) and he said: What is this, O Mu-adh? he said: O Messenger of Allaah, I saw them in Syria prostrating to their bishops and patriarchs, and they narrated that from their Prophets. He said, They are lying, O Mu-aadh. If I were to command anyone to prostrate to anyone else I would have told the women to prostrate to their husbands because of the greatness of their rights over them. O Mu-aadh, do you think that if you pass by my grave you will prostrate? He said, No. He said:(PBUH) Do not do that.

Shaykh Ibn Baaz (may Allah have mercy on him) said:

Prostration is for Allah alone, and the law of Muhammad (blessings and peace of Allah be upon him) is the most perfect and most complete of laws, according to which it is not permissible to prostrate to anyone or anything other than Allah, either by way of greeting or by way of worship. As for worship, it cannot be devoted to any except Allah alone, according to all laws and teachings, but in the past prostration was used as a greeting and by way of honouring people, as the parents and brothers of Yoosuf did, and as the angels did to Adam. This was by way of greeting and showing respect, not by way of worship. But according to the law of Muhammad (blessings and peace of Allah be upon him), Allah, may He be glorified and exalted, has forbidden that and has made prostration for Allah alone, may He be glorified and exalted; it is not permissible to prostrate to anyone else, either the Prophets or others, to the extent that Muhammad (blessings and peace of Allah be upon him) forbade anyone to prostrate to him and stated that prostration is for Allah alone, may He be glorified and exalted.
