This is mentioned in Al Ifada min Tarikhul Aimmatus Saadah [2] Abu Hilal Hasan bin Abdullah Askari in his book, As Sana’teen has quoted the statement of the Imam in this way: “People have become slaves of the world and religion is a meaningless thing on their tongues, till their life passes in comfort they follow it and when hardships befall them, very few remain religious. the thin sediment at the bottom of a drinking vessel. Life is a mean food, like a pasture covered with bad grass.

Do you not see that the truth is not followed and falsehood not discouraged? The faithful must certainly desire to meet his Lord righteously.

I do not deem death other than martyrdom and life among the unjust other than degradation.” [1] In these sentences the Imam has again spoken of the hardships and difficulties that fell upon His Eminence and he informed them that as much hardships increase His Eminence shall not hesitate in his determination and resolve for the establishment of truth for which he had stepped forward. Imam (‘a) did not sermonize his companions to arouse their emotions or to attract their support.

Because what could they have done for him while the armies had filled the desert and surrounded His Eminence. He spoke thus in order to make them aware of their responsibilities of establishing truth and to make them determined for an everlasting success and make them willing partners in this mission. While His Eminence had made the desire of death a part of his life, that nothing else could equal it.

When His Eminence concluded his discourse all his companions arose and expressed astonishing examples of loyalty and sacrifice for the sake of justice and truth... The first one to speak up from his companions was Zuhair Ibn Qain. He was that valiant fighter who had no equal in the world. He said, “O son of Allah’s Messenger, we heard your discourse.

If the world had remained for us and we had become immortals in it we would have given preference to fight for you rather than stay in it.” These statements show the nobility of man in his march on the path of righteousness. Zuhair’s words imparted a great joy and satisfaction to the companions of the Holy Imam and he motivated them to loyalty and sacrifice. Now another valiant companion of the Imam, Burair stood up, who had dedicated his life to the path of God.
