He traveled a day and night then the Prophet said to ‘Ali: Follow Abu Bakr take Bara-ah from him and deliver it and send Abu Bakr back to me. Abu Bakr came back crying. He said: Messenger of God did any revelation come down concerning me? The Prophet said: None but good.
No one should deliver for me except myself or a man from me or he said: from the members of my House..."[^7] Whether the Messenger sent Abu Bakr with the chapter of Bara-ah or the chapter came down after he left for the pilgrimage; and whether Abu Bakr went back to the Prophet or he continued in his leadership of the pilgrimage these hadiths unanimously agree that the Messenger declared that no one should deliver for him (or perform for him) but a man from him or a man from the members of his House (and the first two hadiths and the hadith of Ibn Abbas stated that this was by order from God.) That man was ‘Ali Ibn Abu Talib.
Let us try to understand what the Messenger meant by his saying "No one should deliver for me except a man from me (or from the members of my House).". The Holy Prophet did not mean that no one should report his word or deed except a man from the members of his House; otherwise it would be forbidden for people from outside his House to report what he said or did and this is untrue. The Messenger used to say: "Let the present inform the absent.".
Nor did the Messenger mean that he should not send a messenger to people except a man from his House because he sent many messengers to kings and princes and tribes and individuals and none of them were from the members of his House. The rest of the people can report the words and the deeds of the Holy Prophet. But what they report would not be securely free of error. Many times the reporters themselves became confused and they contradicted each other in their reports.
Therefore none of them would be an authority to the Muslims in representing the Messenger and in replacing him as the communicator of the Islamic instructions. The one who represents the Holy Prophet is a man from the members of his House. The one who delivers for the Messenger and represents him should be the treasurer of the Knowledge of the Mes- senger knowing all of what was revealed to the Messenger and what the Messenger gave of instructions.
This is exactly what the Messenger meant when he said: "I am the city of knowledge and ‘Ali is the gate of that city. Whoever wants to enter that city should come through the gate.".
