Muhammad said: The 'sabigh' (all-encompassing/ample) is that which covers everything beneath it, to the point that it exceeds [in length]. It is mentioned because it points to the object described. The meaning of 'sard' is weaving. 'Sard' is also used for a chain-mail hauberk. It is said for a maker of armor: 'sarrad' and 'zarrad', as the 'za' is substituted for the 'sin'.
