Does the lightness of the coffin indicate the righteousness of the deceased?
We can tell of no reason for the alleged lightness or heaviness of coffins in which the dead are laid down. Lightness or heaviness can only be sensed through tangible reasons like the thinness or fatness of the deceased. There is nothing in the Shari`ah of Islam to lend support to the idea that lightness denotes the righteousness of the deceased and that heaviness indicates his unrighteousness. The movement of the coffin is an indication that the person is still alive, in which case he has to be brought to a specialized doctor for examination. People should not hasten to bury him until he is certainly proved to be dead.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family and Companions.
