Who is Lugman? I have no idea. He’s not in the Bible or Torah. There is a Wikipedia page about him. Here’s one hadith:
Malik related to me that he heard that someone said to Luqman, “What has brought you to what we see?” meaning his high rank. Luqman said, “Truthful speech, fulfilling the trust, and leaving what does not concern me.”
Sunnah.com
There are more hadith that are supposed to be about Luqman but they seem to be Muhammad pretending.
Chapter 31 of the Koran is supposedly named after “Luqman”.
There are some verses in the Koran about him:
And We had certainly given Luqman wisdom [and said], “Be grateful to Allah.”
And whoever is grateful is grateful for [the benefit of] himself.
And whoever denies [His favor] – then indeed, Allah is Free of need and Praiseworthy.
Koran 31:12
There’s a tafsir about this verse which seems to have more invented details about him.
And [mention, O Muḥammad], when Luqmān said to his son while he was instructing him, “O my son, do not associate [anything] with Allāh. Indeed, association [with Him] is great injustice.”
Koran 31:13
31:16 [And Luqmān said], “O my son, indeed if it [i.e., a wrong] should be the weight of a mustard seed and should be within a rock or [anywhere] in the heavens or in the earth, Allāh will bring it forth. Indeed, Allāh is Subtle and Aware. 17 O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] resolve. 18 And do not turn your cheek [in contempt] toward people and do not walk through the earth exultantly. Indeed, Allāh does not like everyone self-deluded and boastful. 19 And be moderate in your pace and lower your voice; indeed, the most disagreeable of sounds is the voice of donkeys.”
Koran 31:16-19

“Be grateful to Allah”

Allah gives nothing, not the rain, not your life. Thus no need to be grateful to the idol Allah.
“Allāh will bring forth”

I’ll say something that is “wrong” in Islam. It’s very quiet, no one heard or saw me. I haven’t told you, the reader, what this is. Here’s a space for Allah to bring it forth:
Allah’s voice:
Allah
I gave Allah several days to “bring forth” this “wrong”.
Nothing happened.
I whispered: “Allah is an idol.”
“do not associate [anything] with Allāh”

This is obviously a great wrong in Islam. Allah did nothing, showing he’s an idol, just like his wife, their three daughters, a pet lion and 360 idols (one for each day) around the pagan temple, the Kaaba.
Muhammad modified his native polytheism into monotheism – this is why: “do not associate [anything] with Allāh”.
“establish prayer, …right, …wrong, …patient”

Which direction, what prayers, when and how often?
As for right and wrong, obviously, Muhammad’s listeners already knew this, right? Thus what was the point?
As for being patient, Muhammad failed this, as he invaded Mecca and made it polytheist and pagan, worshipping the black stone, while removing all the other idols he didn’t like.
“do not turn your cheek”

Christianity:
38 “You have heard that it was said, ‘Eye for eye, and tooth for tooth.’ 39 But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. 40 And if anyone wants to sue you and take your shirt, hand over your coat as well.
NIV Matthew 5:38-40
Obviously, Islam is incompatible with Christianity, and thus, Islam is false.
“do not walk through the earth exultantly”

The Bible does it better:
Humble yourselves before the Lord, and he will lift you up.
NIV James 4:10
“be moderate in your pace”

Obviously, this is stupid.
“lower your voice”

Obviously, this is stupid.
If only Muhammad had listened to himself.
Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, the Koran.
