Banu Amir

Banū ʿĀmir ibn Ṣaʿṣaʿa () was a large and ancient Arab tribe originating from central Arabia that dominated Najd for centuries after the rise of Islam. The tribe is an Arab Adnanite tribe and its lineage is traced back to Adnan and Ishmael son of Abraham through Hawazin, and its original homeland was the border area between Nejd and Hejaz in Khurmah and Ranyah. Although the Banu 'Amir were engaged in a long war with the Quraysh before the appearance of Islam, manifesting in particular as the Fijar War, the tribe was characterized by giving late allegiance to Muhammad and his immediate successors. the tribe produced several well-known Arabic poets, the most famous of whom was Labid ibn Rabi'ah, an author of one of the Seven Hanged Poems. Other poets included 'Amir ibn al-Tufayl, an important tribal chief; al-Ra'i al-Numayri, an opponent of Jarir; and the female poet Layla al-Akhyaliyyah. The protagonists of the romantic saga of Layla wal Majnun, Qays and Layla, also belonged to Banu 'Amir.

In addition to the Uqaylid tribes of Iraq, the modern tribes of Subay', the Suhool in Nejd, and some sections of Bani Khalid trace their lineage to Banu 'Amir.
Military campaigns during Prophet Muhammad's era.
The tribe was involved in military conflict with Muhammad. Four months after the Uhud battle, a delegation of Banu Amir came to Muhammad and presented him with a gift. Abu Bara stayed in Medina. Muhammad declined to accept that gift because it was from a polytheist and asked Abu Bara to embrace Islam. He requested Muhammad to send some Muslims to the people of Najd to call them to Islam. At first, Muhammad was quite apprehensive of this, as he feared that some harm might befall on these Muslim missionaries. On Muhammad's hesitation, Abu Bara guaranteed the safety of the emissaries of Muhammad.
The Muslim scholar Tabari describes the event as follows:
Ibn Ishaq's Biography claims that forty men were sent to them; but Sahih al-Bukhari states that there were seventy — Al-Mundhir bin ‘Amr, one of Banu Sa‘ida, nicknamed ‘Freed to die’ — commanded that group, who were the best and most learned in the Qur'an and jurisprudence.
Muhammad also ordered the Expedition of Shuja ibn Wahb al-Asadi in June 629 with the purpose of raiding the Banu Amir tribe to plunder camels.
