It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The people of Hell will be made so huge for the Fire (for the sake of punishment) that the distance from the lobe of one's ear to his shoulder will become equal to a journey of seven hundred years, the thickness of his skin will be forty cubits, and his molar tooth will be bigger than (the mountain of) Uhud."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Yahya except Imran."
