these are the Ahl Muhammad (another version says aal (family) Muhammad, so, shower your blessings and favours on aal Muhammad as you showered them on aal Abraham; You are the Praiseworthy, the Glorious." Umm Salama said that she raised the cloak to join them, but the Prophet pulled it out of her hand and said: "You are (also) on the right."(1) On many occasions (s.a.w.) explained the meaning of this verse (of purity) to the Muslims and drew their attention to its significance in order to be enlightened with them (Ahlul-Bait) by following their straight path.
Once, it happened that the Prophet while passing his daughter Fatima's (a.s.) house on his way to the mosque for the (lawn prayers, used to call: "To prayer, O Ahlul-Bait, to prayer; Allah desires to keep away uncleanness from you, people of the House and make you pure as pure as can be."(2) Anas bin Malik narrated that the Prophet (s.a.w.) used to go to Fatima's house for six months whenever he went out for prayer.
He used to say: "To prayer, O Ahlul-Bait, to prayer; Allah desires to keep a way uncleanness from you, people of the House and make you pure as pure as can be."(3) 2.
The Verse of Affection (Mawadah): "...Say (O' Muhammad unto mankind): I do not ask of you any reward for it (preaching the message), but love for my relatives (Ahlul-Bait)..." Holy Qur'an (42:23) The Messenger of Allah (s.a.w.) explicitly told the Muslims that this blessed verse refers to his Ahlul-Bait, that is; Ali, Fatima, Hasan and Husein and urged them to obey and follow these illustrious personalities after him.
All commentators, traditionists and biographers said that the word 'near relatives of the Prophet' as used, here, refers exclusively to his Ahlul-Bait that is Ali, Fatima, Hasan and Husein. Fakhruddin Razi, while explaining this verse, says: "...and without doubt no one was so near to the Prophet than Fatima, Ali, Hasan and Husein. This is a well-known fact of all chains of narrations, and these are they who are his 'aal'".
Thus, it is an undisputed fact that the words Ahlul-Bait or aal Muhammad (s.a.w.) refer only to the immediate family of the Prophet; his daughter Fatima, son-in-law Ali and his two sons Hasan and Husein and no one else. First: We have already cited some instances of the Prophet's love for his family. Second: No doubt being his only surviving child, Fatima was intensely loved by her father. The Prophet's famous words are a testimony to this fact.
