How are the days of torment in the Afterlife calculated, and do they correspond to the days and hours of this world, or are there different calculations?

Matters of the Hereafter are unseen knowledge that none knows save Allah. It has been reported that the Day of Resurrection will be fifty thousand years long, and that one day of the Hereafter is equivalent to a thousand years. From the foregoing, it is clear that the days of the Hereafter differ from the days of this world, and one must refrain from delving into matters that Allah has not informed us about.
