Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings of Allah be upon him) forbade wrapping oneself in a single garment in such a way that it covers the whole body (ishtimal as-samma’) and from wrapping oneself in a single cloth as a form of ihtiba’ (sitting with knees drawn up and the cloth wrapped around them), and (he also forbade) that a man places one foot over the other while lying on his back.
