Umayr ibn Sa'd al-Ansari

Umayr ibn Sa'd al-Ansari, a Companion of the Ansar, whom Umar ibn al-Khattab sent to the lands of the Byzantines in the year 21 AH ¹.

Umar appointed him over the summer raid (al-sa'ifa), which was the first summer raid. He instructed him to deal gently with Jabala ibn al-Ayham, and to invite him to return to the lands of Islam, on condition of paying the alms and remaining in his religion. Jabala refused to do anything but remain. Umayr reached a place known as al-Himar, a valley, and fell upon its people and laid it waste ¹.

Ibn Hajar gives him his own entry in al-Isaba, no. 6778: "Umayr ibn Sa'd ibn Ubayd ibn al-Nu'man ibn Qays ibn Amr ibn Awf" — so al-Waqidi traced him, followed by Ibn Abd al-Barr; Ibn al-Kalbi instead attached him to his grandfather, saying "Umayr ibn Sa'd ibn Shahid". He was the Ansari of the Aws and Umar's governor over Hims. ²

Ibn Hajar records from al-Baghawi's Mu'jam al-Sahaba that he was called "nasij wahdahu" ("the weave of one alone"), tracing the report to Abu Talha al-Khawlani, and Abu Ya'la transmitted it too; on Ibn Sirin’s authority it was Umar who used to call him that in admiration of him. ² The entry also notes that he was the one who carried the words of al-Julas ibn Suwayd to the Prophet ﷺ. ²

Ibn Hajar corrects an error by Abd al-Ghani ibn Sa'id in al-Mubhamat, who attached to Umayr ibn Sa'd the story of the dates of Umayr ibn al-Hammam; the story belongs to Umayr ibn al-Hammam, who was martyred at Badr. ³
