102. The epithet“barren”has been applied to the day in its metaphorical and not literal sense. :A day is barren if all the plans, hopes and devices remain unproductive in it, or it does not bring forth its night. For instance, the days on which the people of Prophet Noah, the tribes of Aad and Thamud, the people of Lot and of Midian met with their destruction by scourge from Allah, were barren days in this sense, because those days did not bring forth any tomorrow for them, and no device of theirs could avert their doom.
