Selected Sayings of The Holy Prophet of Islam — Page 33
the HolyProphet, peace and blessings of Allah be upon him, said: "The case of a person who observes the limits set by Allah as compared to the one who breaks these limits is like that of a people who cast lots about reserving places in a boat. Some of them are alloted the upper deck while others get the lower. When those on the lower deck need water they have to pass by those who are above them. They suggest, 'If we make a hole in our part of the ship we will not disturb those above us. ' If those on the upper deck let them do as they intend, all of them will be destroyed, while if they stop them, all of them will remain safe. " (Bukhari) 33
