I was reading a book and learnt that Abraham Maimonides added/brought back sujood (as well as other prayers/rituels).
And my mind a little bit confused because his arguments not that much weak, there're good arguments.
His arguments Psalm 99:5,9
"Exalt the LORD our God and worship at his footstool; he is holy."
"Exalt the LORD our God and worship at his holy mountain, for the LORD our God is holy."
And Berakhot 34b:
"It is appropriate, though, for a High Priest to bow at the end of each and every blessing; and for a king to bow at the beginning of each and every blessing and at the end of each and every blessing. This is because the more lofty one’s status, the more important it is to demonstrate his subservience to God."
2 Chronichles 7:3
"When all the Israelites saw the fire coming down and the glory of the Lord above the temple, they knelt on the pavement with their faces to the ground, and they worshiped and gave thanks to the Lord, saying,
“He is good;
his love endures forever.”"
But some conservative Jews around that time seems objected because they said Abraham Maimonides was effected by muslims and they used Chullin 41a
"שֶׁלֹּא יְחַקֶּה אֶת הַמִּינִין" "he will not appear to emulate [yeḥakkeh] the heretics."
So my question is: Are any of the practices or liturgical customs introduced by Rabbeinu Avraham ben ha-Rambam (Abraham Maimonides) still observed today by any Jewish group?
If they are not practiced, what were the main Halakhic reasons for their abandonment, and what was the rabbinic opposition to them at the time? Because it appears he advocated for full ablution including washing the feet (Netilat Raglayim), whereas today I only see Netilat Yadayim (washing of the hands).
