You shall not make Any Idols
As already discussed in the First Commandment, Mohammad (PBUH) broke the Second Commandment when he made an idol out of the Black Stone. As such, I will just repeat what I wrote:
Ishaq:530 "The Prophet stroked and kissed the Black Stone. Then he went out trotting around the Ka'aba as did his Companions. When the Temple concealed Muhammad from the Meccans and he had "istalama" (which means to embrace, stroke, and kiss) the southern corner of the Ka'aba, he walked to "istalama" the Black Stone a second time. Then he "harwala" (which means to trot or prance swinging the shoulders side to side in a gloating manner) similarly for three circumambulations. He walked the remainder of them. The Apostle only did this to show off in front of the Quraysh.
Mohammad's (PBUH)actions are also confirmed in the Hadith, where Muslims, following Mohammads (PBUH) perfect example, by praying to the Black Stone of the Kaba (which is an idol):It is reported in Bukhari (1520), Sahih Muslim (1720) that Umar approached the Black Stone and kissed it. Then he said: “I know that you are a mere stone that can neither harm nor do any good. If I had not seen the Prophet (sallallahu alaihi wa-sallam) kissing you, I would have never kissed you."SO Mohammad (PBUH) did not pray to the Moses' God, performed all of these pagan rituals and misrepresented that it was from Moses' God, and thus ultimately, broke the Second Commandment.
