in Edition Clear Qur'an by Talal Itani / Luqman (Luqman)

31:7And when Our Verses are recited to him, he turns away in pride, as though he did not hear them, as though there is deafness in his ears. So inform him of a painful punishment.

31:13When Luqman said to his son, as he advised him, “O my son, do not associate anything with God, for idolatry is a terrible wrong.”

31:21And when it is said to them, “Follow what God has revealed,” they say, “Rather, we follow what we found our parents devoted to.” Even if Satan is calling them to the suffering of the Blaze?

31:32When waves, like canopies, cover them, they call upon God, devoting their religion to Him. But when He has delivered them to dry land, some of them waver. No one renounces Our revelations except the treacherous blasphemer.

31:33O people! Be conscious of your Lord, and dread a Day when no parent can avail his child, nor can a child avail his parent, in anything. The promise of God is true. Therefore, do not let this life deceive you, nor let illusions deceive you regarding God.
