Hell will be brought on the day of Resurrection
Ibn Mas’ud (radi Allahu anhu) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “Hell will be brought on that Day (the Day of Resurrection) with seventy bridles; and with every bridle will be seventy thousand angels, pulling it.”
This Hadith deals with the hidden matters relating to the Unseen world. Muslims are ordained by Allah to believe in them. It is wrong to hold them as metaphorical. They are realities but we cannot imagine them.
And Allah Knows Best!
