It is stated in another narration that Imam told Zuhayr bin Qayn and Sa’eed bin Abdullah to stand in front of him so that he may lead the Zuhr Prayers. They did so while Imam lead the Prayers with half of his companions.
It is related that Sa’eed bin Abdullah Hanafi stood in front of the Imam and thus became the target of their arrows. Wherever Imam would turn, Sa’eed would stand in front of him until he was totally wounded and then fell down. He said, “O Allah! Send your curse upon them similar to the tribes of Ad and Thamood. O Allah! Deliver my greetings to Your Prophet, and make him aware about the pain and wounds that I have borne, for I crave Your reward while defending the progeny of Your Prophet.” Saying this he breathed his last (May Allah’s Mercy and Blessings be upon him). Thirteen wounds of arrows were upon his body, apart from the wounds of lances and swords.
Ibn Nima says that some say that Imam Husayn (a.s.) and his companions recited the Prayers individually with signs.
Tabari, Ibn Aseer and others state that after finishing the Zuhr Prayers, they attacked fiercely and neared Imam Husayn (a.s.). Then Sa’eed stood armoring the Imam and defended him from all sides thus becoming a target of the enemies. Arrows started coming from all sides until he fell down. It is written in the related salutations of the Martyrs: Peace be upon Sa’eed bin Abdullah Hanafi, who, when Imam gave them permission to leave him, said, “No, by Allah! We shall not leave you alone.” Then you faced your death and defended your Imam, and you witnessed the grace of Allah in the place of residence. May Allah gather us along with you in the ranks of the martyrs. And may Allah provide us your friendship in the exalted position of the magnificent ones.
