Sleeping on the ground for forty days as mourning over the dead

A: What is mentioned regarding moving the dead person to the graves after shrouding them at a distance of one meter, then putting them down on three stages has no basis (in Islam). Likewise is the remembrance that is said out loud when moving the deceased, for all these are acts of Bid`ah (innovation in religion).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
