Abu Sai’d al-Khudri reported: The Messenger of Allah, peace and blessings be upon him, said, “A bridge will come and be placed across Hell.” We said, “O Messenger of Allah, what is the bridge?” The Prophet said, “It is shaky and slippery, over which are claws, pincers, and broad spikes with curved thorns like the seed found in Najd known as al-Sa’dan. The believer will cross over it like the blink of an eye, or like lightning, or like wind, or like powerful horses, or like camels. Thus, one will be unharmed, another will be lacerated, and another will plunge into the fires of Hell, until the last one will be dragged across it.”
