His name is "Qais bin Mashar bin Khulaid bin Jundub bin Munqith bin Jisr bin Nakrah bin Nawfal bin al-Saida," from the tribe of "Bani Amr al-Sidawi," a branch of Bani Asad tribe.
He was an honorable man in his tribe, a brave and loyal to the Prophet Muhammad's household "peace be upon them."
The famous companion "Abu Makhnaf" said "Al-Husayn (peace be upon him) called on his messenger (Muslim bin Aqeel), and send him with Qais bin Mashar al-Sidawi, Abd al-Rahman bin Abdullah bin al-Kadun al-Arhaby, to the people of Kufa."
"Muslim" came then to Medina, as he prayed in its mosque, then he hired two guides from Qais tribe. However, they lost the way, and became very thirsty, until the two guides him that this road ends with water source.
Therefore, Muslim sent a letter with Qais bin Mashar to al-Husayn, to tell him about this ordeal, and to take the Imam's answer.
According to the historian "Al-Tabari", "Qais bin Mashar al-Sidawi took the letter to Kufa, and when arrived to Qadisiyah town, a leader named (Husayn ibn Tamim) took him to the tyrant Ubayd Allah bin Ziyad, who told him to curse Imam Al-Hussein, but his answer was to shout from roof of Ubayd Allah's palace, (O people, Imam Hussein bin Ali is the best of God’s creation, he is the son of Fatima, the daughter of the Messenger of God, and I am His Messenger to you, so pledge your allegiance to him,) so Ubayd Allah bin Ziyad ordered his guards to throw him from the palace, so he died.
