The Messengers only duty was to deliver Allah's message which was the Quran and establish Islam in the region outside of that he did not did not give any additional commands of his own. And to follow the prophets dietary regime of how many times he ate, how many dates he broke his fast with or what side did he sleep on, so on and so forth. Is really inconsequential and does nothing but take away from the message of god which is in the Quran and not in the Prophets daily life routine.
What we have done and specially in our desi lands, we have made our religion around the Prophet based on unverified and dubious claims from the hadith. What we haven't done is adopt the actual religion which was given to us in the Quran.
Islam specially in the asian subcontinent is now relegated to dogmatic rituals.
