The Messenger of Allah (peace and blessings of Allah be upon him) said: “The example of the righteous who observe the limits of Allah and encourage others to do the same, and those who neglect to forbid evil and evil, is like a group of people who board a ship. Some of them are placed on the top of the ship and some on the bottom. When those on the bottom need water, they pass by those on the top. Then they say: “Why don’t we make a hole in our part (of the ship) so that we don’t bother those on the top?” If those on the top do not prevent them from doing so, then those on the bottom and themselves will perish. If they are prevented, all of them will be saved.” (Narrated by al-Bukhari)
