Banu Jadhimah were notorious during the
Jahiliyyah (pre-Islamic era) for their extreme violence and were infamously known as "the lickers of blood." Among those they reportedly killed were al-Fakih ibn al-Mughira and his brother, both uncles of
Khalid ibn al-Walid, as well as the father of
Abd al-Rahman ibn Awf. They were also responsible for the deaths of Malik ibn al-Sharid and his three brothers from
Banu Sulaym in a single incident, along with others from various tribes. In the year 8 of the Hijrah, Khalid was dispatched by
Muhammad to invite the Banu Jadhimah to
Islam. Khalid persuaded the tribesmen to disarm and embrace Islam. The tribesmen responded to Khalid's call with the phrase “saba’na, saba’na,” meaning "We have become Sabeans," a term understood as a general declaration of conversion. However, due to his unfamiliarity with their accent, Khalid misunderstood this as a rejection of Islam and ordered their execution. When Muhammad learned of this incident, he declared to God that he was innocent of Khalid's actions. He sent
Ali ibn Abi Talib to pay compensation to the survivors. Despite this, Muhammad did not discharge Khalid or punish him, and he continued to entrust him with command over other expeditions. ==Islamic sources==
