Ritual purification
Useful information:
The Verse of Purity (taharah): "Allah only desires to keep away uncleanliness from you, O People of the House ( ahl al-bayt ), and to make you as pure as possible."Qur'an 33:33 ]
The prominent scholars of Islam and the narrators of the Prophetic tradition unanimously agree that ahl al-bayt (the household of the Prophet ( pbuh&hf )) which Almighty Allah uses in the Holy Qur'an refers to the daughter of the Holy Prophet ( pbuh&hf ), Lady Fatima al-Zahra' ( pbuh ); his cousin, 'Ali ibn Abi Talib ( pbuh ); and their children Hasan and Husayn ( pbut ). [ al-Durr al-Manthur , al-Suyuti]
Tabarani narrates from one of the respected wives of the Holy Prophet ( pbuh&hf ), Um Salamah, that the Messenger of Allah ( pbuh&hf ) once told his daughter Lady Fatima ( pbuh ) to call her husband 'Ali and their two sons, Hasan and Husayn. When they came, the Messenger of Allah ( pbuh&hf ) covered them with a cloak, put his hand on them, and said: "O Allah, these are the Al-i -Muhammad (the family of Muhammad), so shower Your blessings and favors upon the Al-i- Muhammad just as You showered them on the Al-i- Abraham. You are the Praiseworthy, the Glorious." Um Salamah says that she raised the cloak to join them, but the Holy Prophet ( pbuh&hf ) took it from her hand, saying: "You are also on the right."
