9. That is, “The events of a thousand years of your history are a day’s work for Allah.” He entrusts His scheme of work to the “angels of destiny”, who submit their report of work before Him and receive orders for the scheme of the next day (whose length according to your calculation would be a thousand years). This thing has also been expressed at two other places in the Quran, the study of which can help understand it. The disbelievers of Arabia said, “Muhammad (peace be upon him) claimed to be a Prophet many years ago. He has warned us again and again that if we did not accept his message and rejected his invitation, we would be seized by Allah’s torment. He has been repeating this threat since many years, but the torment has not overtaken us, although we have denied and rejected him clearly over and over again. Had his threats any substance in them, we would have been seized in the torment long ago.” In this connection, in Surah Al-Hajj Allah says: “These people are demanding of you to hasten the chastisement. Allah will never fail to fulfill His threat, but a day with your Lord is equal to a thousand years as you reckon.” (Ayat 47).
In Surah Al-Maarij (Ayats 1-7), it has been said: “An asker has asked for a torment, (the torment) which must befall the disbelievers. There is none to avert it. It is from that God Who is the Owner of the Steps of Ascent. The angels and the Spirit ascend to His Presence in a day whose measure is fifty thousand years. So, have patience, O Prophet, a graceful patience! They think it is far off, but We see it near at hand.”
What is meant to be impressed in these verses is this: Allah’s decrees are not passed and enforced in the history of mankind according to the earthly watches and calendars. When a nation is warned that if it adopted such and such an attitude in life, it would meet with such and such an end, the people would be foolish if from this they understood that the predicted consequences would follow their evil acts and deeds immediately. Not to speak of days and months and years, the occurrence of the results may even take centuries.
