Luqman (as) Advices His Son:

"O My Son!
Join not in worship (others) with God:
for false worship is indeed the highest wrong-doing
Show gratitude to Me & to thy Parents
Love - Thanks - Obedience - Respect

"My Son!
"If there be (but) the weight of a mustard seed & it were (hidden) in a rock or (anywhere) in the heavens or on earth, God will bring it forth: for God understands the finest mysteries (&) is well acquainted (with them)." 
Knowledge of Allah (swt)

"O My Son!
Establish regular prayer, enjoin what is just & forbid what is wrong."
And bear with patient constancy whatever betide thee; for this is firmness (of purpose) in (the conduct of) affairs,"
And swell not thy cheek (for pride) at Men, nor walk in insolence through the earth; for God loveth not any arrogant boaster,"

The boastful person can deny & not admit other's right; He considers others like a seed because he thinks he is top most" (Ibn Masûd (ra) said: Prophet Muhammad (saw) said: no one will enter the Garden since his heart contains a weight of a seed of boastfulness", & a man asked: "If a
man likes his clothes & his shoe to be
beautiful? " And the Prophet (saw) said: "Allah is beautiful & He likes the
beauty, the boastfulness is to deny, to scorn what is just & to depreciate People.")
Muslim

"And be moderate in thy pace,"
"And lower thy voice; for the harshest of sounds without doubt is the braying of the donkey»."
It was related that Anas (ra) said:
Prophet Muhammad (saw) said: the High Majestic said: "I have 4 qualities which one of them is Mine, the 2nd is for You, the 3rd is between You & Me & the last one is between You & My Servants
*What is Mine: to not worship other along with Me;
*What is Yours: if You do good deeds, I will reward You;
*What is between You & Me: To pray (Du'a) & the acceptance is Mine;
*And what is between You & My Servants: To like to Themselves what
You like to Yourself."
