What can we learn about the Prophet Muhammad (saw) from the hadith narrated by 'A'isha that he (saw) took a bath from a vessel containing seven to eight seers?
 'A'isha reported:                      The Messenger of Allah (may peace be upon him) took a bath from the vessel (which contained seven to eight seers, i. e. fifteen to sixteen pounds) of water And I and he (the Holy Prophet) took a bath from the same vessel. And in the hadith narrated by Sufyan the words are:" from one vessel". Qutaiba said: Al-Faraq is three Sa' (a cubic measuring of varying magnitude).
