Hadith.70 - The Messenger of Allah (sw) said: "Ablution (wudu) is a mud (a specific measure), and ghusl (ritual washing) is a saa' (a larger measure). There will come people after me who will underestimate these amounts, and those will be contrary to my Sunnah. The one who adheres to my Sunnah will be with me in the enclosure of holiness (Paradise)."
