Abu Thumamah al-Sa'edi, one of the great companions of Imam al-Hussayn (peace be upon him).

Abu Thamamah Amru ibn Abdullah Al-Sa'edi, the companion who recalled the prayer, was a supporter of the Master of the martyrs (peace be upon him) and one of his loyal soldiers who were martyred in front of him in the at-Taf immortal battle. The name of this companion is immortalized in the pages of Islamic history as a hero who has melted in love with his master and the Imam of his time.
He was (may Allah be pleased with him) the one who mentioned prayer amid the flare-up of war, and he asked Imam al-Hussayn (peace be upon him) the permission to face martyrdom for his redemption, wishing that he meets the Almighty after performing the noon prayer. Imam (peace be upon him) raised his head towards the heavens and said to him: “You mentioned Salah [prayer], may Allah make you from those who pray (musalleen) who remember Him, yes indeed, the beginning of its time; request them to stop so that we may pray.”
Thus, these are the Hussaynis in every time and place, the first to establish the rituals of Allah Almighty and perform his worship, even if the death approaches. The father of the free; Imam al-Hussayn (peace be upon him) made his sacrifice so the Muslims continue the worship ordered by Allah Almighty and called by His Messenger Mohammad (Allah's prayers be upon him and be upon his holy household) .
