My father narrated to us. He said: Al-Husayn b. Muhammad b. `Amer narrated to us from al-Mu`alla b. Muhammad al-Basri rom Ja`far b. Sulayman from `Abdullah b. al-Hakam from his father from Sa`id b. Jubayr from Ibn `Abbas. He said:

The Prophet (s) said: Surely, `Ali is my deputy and my vicegerent. His wife, Fatima, the Mistress of the Women of the Worlds, is my daughter. Al-Hasan and al-Husayn, the two Masters of the Youth of Paradise, are my two sons. Whoever aligns with them has aligned with me, and whoever opposes them has opposed me, and whoever defies them has defied me, and whoever is neglectful of them is neglectful of me, and whoever is good to them is good to me. Allah will connect with whoever connects with them, and He will cut off whoever cuts them off, and He will support whoever aids them, and He will cause failure to whoever fails them. O Allah! Each of Your prophets and Your messengers had a heavyweight and a family. So, `Ali, Fatima, al-Hasan, and al-Husayn are my family and my heavyweight; so, remove all uncleanliness from them, and purify them with a thorough purification.
