Overall meaning : Almighty Allah says: On that day, people’s faces will be humbled before their Creator, the Ever-Living, All-Sustaining God, who sustains all things and manages all affairs. Those who come on Judgement Day burdened with the sin of associating partners from among Allah’s creation with Him or with acts of disobedience will be the losers that day.
Then, giving glad tidings to the faithful, He says: Those who do good deeds while believing in their Lord will fear no wrong by having their bad deeds increased, nor will they fear any injustice by having their good deeds decreased in any way.
Next, He mentions the language in which the Qur’an was revealed and some reasons for revealing it: Thus have We sent it down in the Arabic tongue so that its meanings may be understood, and We have repeatedly expounded warnings in it in various ways so that they may fear their Lord, or that this Qur’an may cause them to take heed.
Then He praises Himself, saying: High exalted be Allah, and far removed be He from all defects and imperfections, the Ultimate Sovereign whose ultimate power has subdued every king and mighty one, and the Ultimate Truth in every respect!
After that, He enjoins His Prophet not to hasten to repeat the words of the Qur’an and directs him to pray to Him for increased knowledge: Do not hasten, Muhammad, to recite and memorise what Gabriel recites to you before he finishes his recitation, and pray, ‘Lord, increase my knowledge.’
