Sulaym bin Amir narrates that Sayyiduna al-Miqdam bin Ma'di Karib (may Allah be pleased with him) told them that the Messenger of Allah (peace and blessings be upon him) said: "No one dies, whether a stillborn child or a very old person - and people are only between these two extremes - except that he will be raised at the age of thirty. Whoever is from the people of Paradise will have the stature of Adam (peace be upon him), the form of Yusuf (peace be upon him) and the heart of Ayyub (peace be upon him); and whoever is from the people of Hell will be made huge and massive like mountains."
