The time of Allah (swt) is incomparable to the earthly time.The verse from Surah Hajj reads as:
"Yet they ask thee to hasten on the Punishment! but Allah will not fail in His promise. Verily a Day in the sight of thy Lord is like a thousand years of your reckoning".
[Al-Qur’an 22:47]
When the unbelievers asked to hasten the punishment the Qur’an says Allah will not fail in His promise. Verily a period in the sight of Allah is like a thousand years of your reckoning.

When we look at this verse critically, it is obvious that Allah has not yet counted a day in our own counting this is simply because, the life span designed for Human beings, animals, trees etc. cant reach the age stipulated. the only existing things we can say has survived this age are; lakes, rivers, springs, beaches, oceans, heaven and hearth and some unseen creatures. Allah in his infinte mercy, has designed everything according to period and time. Maybe it is when Allah has counted 5 days will be the due time for the ascetion of Jusus in the second heaven, no one knows. from this, we will now clearly see how it is taking too much long in our own counting for the second coming of jesus, but in His own counting, it is not. may Allah be pleased with you.
