Will the Day of Reckoning be a single day?

The Day of Judgment is a single day, the duration of which is fifty thousand years. It will be a difficult day for disbelievers and an easy one for believers. One should accept matters of the unseen and take them at their apparent meaning without delving deeply into them, because the affairs of the Hereafter differ from the affairs of this world, and their full reality cannot be comprehended in this life, just as the attributes of Allah Almighty are not comparable to any of the attributes of creation.
