الآية رقم (19) - وَفُتِحَتِ السَّمَاء فَكَانَتْ أَبْوَابًا

(19) - (And the heaven is opened and will become gateways (19))

Thus, a universal upheaval will take place but we do not know how or when the doors of the skies will open, as this is of the unseen that Allah (swt) tells us about when describing the scenes of the Day of Judgment.
