Overall meaning : God Almighty states that the observance of the Sabbath, by devoting it to worship and refraining from all work, was only ordained only on the Jews as punishment when they differed with their prophet concerning it. They were ordered to devote themselves solely to worship on Friday but they would not obey, and declared that they would observe Saturday, which they considered to be the best of all days. Then, addressing His Prophet, Muhammad, may Allah bless him and grant him peace, He says, ‘Your Lord will judge between them on the Day of Judgement regarding their differences and repay them according to what they deserve.’
Then He enjoins him to invite people to His religion: Call all mankind to the religion of your Lord with wisdom and good advice that softens the heart and refines the soul, and argue with the stubborn among them in the kindest and gentlest manner; Indeed, Allah best knows those who stray from His path and do not follow His religion, and He best knows the rightly guided who follow it.
The Almighty then appoints out the right course of action a Muslim must take when any form of aggression is launched against him and his faith: If you should punish those who assault you and commit any act of aggression against you, then let your punishment be commensurate with the wrong done to you. After allowing the faithful to repel aggression within the limits of justice, He shows them yet a better course of action: But if you exercise patience by forgiving them and desisting from taking your revenge on them, patience is then far better for you than retaliation in Allah’s sight.
Be patient, Muhammad, when calling people to your Lord’s religion and patiently bear the harm that is bound to be done to you while doing so; none but Allah will grant you patience. Do not be sad because of their turning away from your call and persistently refusing to follow the true religion; nor be distressed by their unbelief, enmity and evil schemes, for He will surely make you prevail over them. Indeed, Allah is with those who obey Him by doing what He commands and avoiding what He forbids and is with those who perfectly worship Him and do good to people. He gives them help, support, success and victory.
