(a) It is narrated from Sayyiduna Qays bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) went to visit them. They placed water for the ritual bath for him (peace and blessings be upon him), and he (peace and blessings be upon him) bathed. Then he was given a cloth dyed with saffron, and he (peace and blessings be upon him) wrapped himself in it.
(b) Sayyiduna Qays bin Sa'd (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) came to us. We placed water for the ritual bath for him, and he (peace and blessings be upon him) bathed. Then we brought him a cloth dyed with wars (a yellow plant dye), and he (peace and blessings be upon him) wrapped himself in it; it is as if I can see the trace of the wars on his neck.
