Safina reported that Abd Bakr, the Companion of the Messenger of Allah ﷺ , observed: The Messenger of Allah ﷺ took a bath with one Sa of water and performed ablution with one Mudd (of water); and in the hadith narrated by Ibn Hujr the words are: One Mudd sufficed for his (Holy Prophets) ablution. And Ibn Hujr said that (his Shaikh) Ismail was much advanced in age, and it was because of this that he could not fully rely on him for this tradition.
