G. Muhammad, peace and blessings be upon him, always held the Name of God (Allah) in the highest of reverence and never took God's Name in vain or for any vainglorious purpose.

He forbid his followers for ever doing anything like this and encouraged them to use names such as Servant of Almighty God (Abdullah).

H. Muhammad, peace and blessings be upon him, upheld the proper worship and ceremonies of his grandfathers, Abraham and Ishmael, peace be upon them. Here is something from the second chapter of the Quran. Read closely;

Recall when Abraham's Lord (Allah) tested him with Commands, that he fulfilled. Allah said, Surely, I am going to make you a leader (prophet) of mankind. (Abraham said) And my offspring, too. (Allah) said, My Covenant (prophethood, etc.) does not include wrong-doers (thalimun).
And recall when (Allah) made the House (ka'bah in Bakkah, which later was called Makkah) a place of resort for mankind and a place of safety. And it is your place of prayer, and (Allah) commanded Abraham and Ishmael to purify (God's House at Makkah) for those who are circling it, or staying there or bowing or prostrating themselves (there, in worship).
And when Abraham said, 'My Lord, make this city (Makkah) a place of security and provide its people with fruits, for them that believe in Allah Almighty and the Last Day.' (Allah) answered, As for him who doesn't believe, I shall leave him in contentment for a while, then I shall compel him t the torment of the Fire, and worst indeed is that destination!
And when Abraham and Ishmael were raising the foundations of the Sacred House (Ka'bah in Makkah), saying, 'Our Lord! Accept from us. Certainly! You are the All-Hearer, the All-Knower.'
Our Lord! And make us sub unto You and of our offspring a nation sub unto You, and show us our Manasik (all the ceremonies of pilgrimage - Hajj and 'Umrah, etc.), and accept our repentance. Truly, You are the One Who accepts repentance, the Most Merciful.
Our Lord! Send amongst them a Messenger of their own (and indeed Allah answered by sending Muhammad peace and blessings be upon him ), who shall recite unto them Your Verses and instruct them in the Book (this Quran) and full knowledge of (Allah's) Laws and jurisprudence, and sanctify them. Verily! You are the All-Mighty, the All-Wise.
And who turns away from the religion of Abraham (Monotheism) except him who fools himself? Truly, (Allah) chose him in this world and verily, in the Hereafter he will be among the righteous.
When his Lord said to him, Submit (Islam means submission)! He said, I have submitted myself (Muslim means one who submits) to the Lord of all that exists.
And this (submission to Allah) was ordered by Abraham upon his sons and by Jacob; saying, O my sons! Allah has chosen for you the (true) religion; then die not except in the Faith of Submission (like those in true submission to God's Will).
[Holy Quran 2:124-132]

I. Muhammad, peace and blessings be upon him, performed these same ceremonies in worship to what we find the prophets doing before him, bowing to toward the ground and prostrating (falling on the face) while praying and worshipping. He would face Jerusalem for his devotionals and commanded his followers to do the same (until Allah sent down the angel Gabriel with revelation to change the direction (
