When Syedi Ibrahim, the noble son of Syedna Hasan passed away in the court of the Malik, he expressed sadness and said that if anyone could be ransomed for the life of Ibrahim, he would ransom with one his own son. During this period, Zaidis were preoccupied with with their internal conflits, but their hostility to Syedna and Moomineen remained continue.

satisfactory answer to him. He was informed about Syedi Hasan Pir as a true and unpeered Aalim. He invited Syedi Hasan pir to his court and he gave him a very satisfactory answer. Afterward, a king of Rome sent three apparantly same head of gold to the the Sultan of Patan and asked that what was the difference among them. No one among the scholars of Court was able to solve the puzzle. Again, Syedi Hasan Pir gave the answer. The Sultan respected him greatly, but the scholars of his court became jealous of him and intrigued to slay him.
