"And (remember) when Luqman said to his son when he was advising him: "O my son! Do not join others in worship with Allah. Indeed, joining others in worship with Allah is the highest wrong-doing."
And we have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is two years – give thanks to Me and to your parents – unto Me is the final destination.
But if they (both) strive with you to make you join in worship with Me others that of which you have no knowledge, then obey them not, but behave with them in the world kindly, and follow the path of him who turns to Me in repentance and obedience. Then to Me will be your return, and I shall tell you what you used to do.
"O my son! If it be (anything) equal to the weight of a grain of mustard seed, and though it be (hidden) in a rock, or in the heavens or in the earth, Allah will bring it forth. Indeed, Allah is Subtle (in bringing out that grain), Well-Aware (of its place).
"O my son! Establish Salah, enjoin al-Ma’ruf (right) and forbid al-Munkar (wrong), and bear with patience whatever befalls you. Indeed, these are some of the important commandments ordered by Allah with no exemption.
"And turn not your face away from men with pride, nor walk (arrogantly) through the eath. Indeed, Allah likes not each arrogant boaster.
"And be moderate (or show no insolence) in your walking, and lower your voice. Indeed, the harshest of all voices is the voice (braying) of the Ass."
