From Rabda, Ali sent envoys to the neighboring tribes to seek volunteers. The Banu Tai were the first to rally to the support of Ali. During the time of the Holy Prophet, Ali had played an important role in espousing their cause, and converting them to Islam. The tribe had particular attachment for Ali, and they enthusiastically responded to Ali's call for volunteers. Saeed b Ubaid, the chief of the Banu Tai waited on Ali and said: "O Commander of the Faithful, there are many persons who do not speak openly what is in their heart, but such is not the case with me. I have always held you in the greatest esteem. I have looked upon you as the leader both openly and inwardly, and have resolved to support you and fight against your enemies whosoever they be. I consider you to be a person of the highest merit, more worthy than any one else of this or any other age to be called a superman."
With these words the chief swore allegiance to Ali, and thereafter the other men of the tribe also swore their allegiance. The men of the Banu Asad allied with Banu Tai also swore allegiance to Ali. Most of the other tribes in the neighborhood chose to remain neutral and not to side with any party at that stage.
