The Messenger of Allah ﷺ said, regarding "and couches raised high" [Waqiah 56:34], "By Him in whose hand my soul rests, their height is like the distance between the heaven and the earth, and between the heaven and the earth is a journey of five hundred years."
وعن رسول الله ﷺ أنه قال {وفرش مرفوعة} والذي نفسي بيده إن ارتفاعها كما بين السماء والأرض وإن ما بين السماء والأرض لمسيرة خمس مائة سنة
