Overall meaning : Allah Almighty says: Do not entertain the slightest doubt, Muhammad, that your idolatrous people follow nothing but falsehood and worship only false gods. They blindly follow in the footsteps of their fathers by worshipping as their fathers worshipped before them, and We will certainly give them their full due for whatever good or evil they have earned, not in the least diminished. We gave Moses the Torah before, but his people disagreed concerning it, splitting into believers and unbelievers, just as your own people have done concerning the Qur’an; and had it not been for a decree Allah had previously issued to give them respite and defer their punishment, He would have delivered His judgement between them, whereby the unbelievers will be destroyed and the faithful will be saved; and those who follow the Torah are still in grave and serious doubt about their book. Your Lord will give each of those differing people, whose accounts We have related to you, their full due on Judgement Day for whatever good or evil they may have done. Your Lord has full knowledge of what they do.
The Almighty then enjoins His Messenger, may Allah bless him and grant him peace, and his followers to staunchly adhere to His religion, saying: Therefore, stand firm, Muhammad, and remain steadfast as you have been commanded, together with those along with you who have turned to Him, and none of you should overstep the limits He has set for you, for He sees all that you do and nothing is hidden from Him, and He will repay you according to your actions. Nor incline towards those who do wrong and approve their evil actions, or the Fire will touch you, and then you will have no one to help you or save you from Allah’s punishment. Duly perform the prescribed prayers, Prophet, at the beginning and end of the day, as well as during parts of the night. Indeed, good deeds wipe out evil deeds. What Allah has hitherto commanded you and forbidden you all to do is a reminder for those who pay heed, seek His reward and fear His punishment. Be patient, Prophet, and persevere in what Allah commands you to do, and patiently bear the harm of your idolatrous people, for Allah does not fail to repay those who do good and will never deny their reward.
