Then he said: I am about to be summoned (by God and I shall respond to His call).

Then he said: I am about to be summoned (by God and I shall respond to His call). I shall be questioned and you will be questioned. Then he said: "Certainly God is my 'Mawla' (Guardian) and I am the guardian of the belevers. Do you not know that I have more authority over you than you have over yourselves? We said: Yes. He said this three times.

Then he held your hand Commander of Believers (the reporting companions were addressing the Imam ‘Ali) and lifted it and said: 'Whoever I am his Mawla (Guardian) this is his 'Mawla'.

God love whoever loves him and be hostile to whoever is hostile to him.' The Imam ‘Ali said to the testifying companions: You have told the truth and I am among those who bear witness to that."[^1] Al-Hafith Muhammad Ibn Abdullah the entitled Al- Hakim Al-Neesabouri in his Mustadrak reported through his channel to Zaid Ibn Arqam that Zaid said: "When the Messenger of God returned from the Valedictory Pilgrimage and stopped at Ghadir Khum he ordered the Muslims to clean under the trees at that place and said: 'I am as if I were summoned and I responded.

I have left in you "Al-Thaqalain " one of them is bigger than the other: The Book of God and my "Itrah" (the close relatives). Beware how you will treat them after me; for they shall not part with each other until they join me at the Basin (on the Day of Judgment). Then he said: Certainly God is my Guardian and I am the Mawla (Guardian) of every believer.

Then he lifted the hand of ‘Ali and said: Whoever I am his Mawla (Guardian) this is his "Wali" (Guardian) God love whoever loves him and be hostile to whoever is hostile to him."[^2] Al-Hakim through another channel reported that Zaid Ibn Arqam reported that the Prophet said the following: "... O people I am leaving in you two elements you will never go astray if you follow them.

They are the Book of God and the members of my House my Itrah.' Then he said: Do you know that I have more authority over the believers than they have over themselves (repeating that three times)? They said: Yes. The Messenger of God said: Whoever I am his Mawla this ‘Ali is his Mawla."[^3] These hadiths contain three important items: The Messenger left to his nation two important elements which do not part with each other and that obedience of the two constitutes a security against straying.

The two elements are: The Book of God and the 'Itrah' (close relatives) of the messenger.
