Mujahid (may Allah have mercy on him) says that once Ibn Abbas said, "Do you know how vast Hell is?" I replied, "No." He said, "Well, indeed you do not know. Between the earlobe and the shoulder of the inhabitants of Hell, there will be a distance of seventy years, and in it, valleys of pus and blood will be flowing." I said, "Rivers?" He replied, "No, rather valleys." Then he asked again, "Do you know how vast Hell is?" I replied, "No." He said, "Well, indeed you do not know. Aisha told me that she asked the Prophet (peace be upon him) about this verse: 'On the Day of Resurrection, the whole earth will be in His grip, and the heavens will be rolled up in His right hand.' So she asked, 'O Messenger of Allah! Where will the people be on that day?' The Prophet (peace be upon him) replied, 'They will be on the bridge over Hell.'"
