And as for the one who believes in Allah and does good deeds, for him is paradise, as a reward from your Lord for his faith and good deeds.
And I shall say to him of my command that which contains ease and lenience”.

"But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)."
