Sayyiduna Jabir bin Abdullah (may Allah be pleased with both of them) narrates: A lahd (niche) was made for the Prophet (peace and blessings of Allah be upon him), and raw bricks were placed over it. The blessed grave of the Prophet (peace and blessings of Allah be upon him) was kept about one span above the ground.
