Overall meaning : The Day of Judgement has drawn near, and the moon has split into two parts in support of the Prophet’s prophethood. Yet, whenever the Quraysh idolaters see a sign bearing witness to the truthfulness of Muhammad’s prophethood, they stubbornly deny it and turn away, saying, ‘What Muhammad shows us is but a continued series of magic!’
They deny the truth and follow their own desires without any proof whatsoever. Yet everything is destined to reach an end in this life and the next and will be ultimately settled. Enough cautionary stories about the destruction of past communities who denied their messengers, have already come to them to serve as a deterrent to them to desist from disbelieving in Allah and denying His revelations and messengers. They contain consummate, far-reaching wisdom, but how can they benefit from warnings when they obstinately reject the clear signs?!
Therefore, turn away from them, Muhammad, as warnings are of no benefit to them; and await the day when the Summoner (Angel Israafeel) will call mankind to something awfully dreadful. They will come forth from their graves, with their eyes downcast because of extreme fear, and make their way go to the Place of Gathering—the Plains of Judgement Day. Numerous will they be as though they were locusts scattered about, obediently hastening towards the Summoner. The unbelievers will, on that day, say, ‘This is a very hard day indeed.’
