Muslim conquest of Levant According to Yemeni historian professor Sulaiman Issa, Amr brought along Zubaidi tribesmen from
Tihamah to participate in the
Muslim conquest of the Levant. In 634 CE, According to
Hisham ibn al-Kalbi, after Khalid ibn Sa'id fell in the
battle of Marj al-Saffar, the sword of al-Samsara previously belonging to Amr was found next to his body.
Mu'awiya therefore took the sword. At one point, Thomas, the garrison commander of Damascus, decided to lead the breakthrough against the siege by assembling forces in the eastern gate more numerous than the other gates, so that Khalid would be unable to move to Shurahbil's assistance and take command in that decisive sector. As the East Gate, the situation also became serious, for a larger Byzantine force had been assigned to this sector, and Rafay ibn Umayr was unable to withstand their attacks. Amr and Khalid then positioned themselves on the front of the eastern gate of Damascus. At first, a Byzantine commander from
Baalbek named Harbees was sent to Homs in response to the Muslims' siege of the city. Amr and Dhiraar then continued by leading more than 5,000 cavalry troops joining Maysarah ibn Masruq to besiege Homs. Later, as the campaign in the Homs governate continued, Amr and about twenty mounted warriors consisted of Dhiraar ibn al-Azwar, Qais ibn Hubairah,
Abd al-Rahman ibn Abi Bakr,
Malik al-Ashtar, Auf ibn Salam, Sabr ibn kalkal, Mazin ibn Amr, Asid ibn Salamah, Rabia ibn Amr, Ikrimah bin Abi Jahl, and others entered the city of
Al-Rastan. During the siege of al-Rastan, it is recorded that the supreme commander of Rashidun, Abu Ubaydah, employed
military deception that allowed Amr and about 20 warriors to enter the city, and to cause chaos once they were inside of the wall while also opening the gate from inside and allowing the Muslim armies to overwhelm the defenders, thus allowing the city to be captured despite its very strong fortification defence.
Battle of Yarmuk Later, Amr ibn Ma'adi-Yakrib was recorded as participating in the
Battle of the Yarmuk, where Amr led soldiers from the
Zubaid clan on the right flank of the Rashidun army. There are record about his remarks regarding the
Ghassanid tribe after the battle.
Muslim conquest of Persia When the Battle of Yarmuk was over,
Sa'd b. Abi Waqqas asked the caliph
Umar ibn al-Khattab to send him reinforcements for the
Battle of al-Qadisiyyah.
Ibn Asakir recorded that according to
Abu Ubayda ibn al-Jarrah, commander of Rashidun army in Levant, Amr was among nineteen veterans that participated in Yarmuk that were sent into Qadisiyyah. Umar took precautions after disaster befell the Rashidun army in the
Battle of the Bridge, and he immediately instructed several commander to send their detachments to go to Qadisiyyah, where the Madhhij contingent sending 1,200 of their fighters led three leaders, which are Amr, Abu Suhra bin Dhu'ayb, and Yazid ibn al-Harith as-Sada'i. Amr was sent along with Tulayha and
al-Qa'qa as commander to
Qadisiyyah. Umar instructed Sa'd to consult Amr and Tulayha regarding military matters, as Umar highly regarded the wisdom of both of them, while in addition, Umar also addressed to Sa'd in his letter:
Battle of al-Qadisiyah After arriving in Qadisiyyah, Sa'ad ibn Abi Waqqas, the supreme commander of Rashidun army in
Iraq, and the Rashidun army in Iraq were rejoiced with the arrival of both Amr and Tulayha, as they were acknowledged by the Qurayshite as heroes who were often hired by the Quraysh tribe to fight their wars in the past, during the era of
Pre-Islamic Arabia. Amr was then sent by Sa'ad as an envoy to
Rostam to give the Sassanids a message, offering Rostam a choice between converting to Islam, surrender and paying Jizya tribute, or war.
Tabari particularly detailed in one chain of narrations the circumstances in which Tulayha infiltrated the Sassanid camps under the cover of darkness, and cut the ropes of the Sassanid rear army tents while bringing torches to ignite the fires within the camp.. The horses, according to Tulayha himself, belonged to Rostam. On another occasion, as Amr roamed between the Rashidun and Sassanid lines on his horse, a Sassanid archer took position in the frontline and shot at Amr, which barely missed, hitting the edge of a bow slung on Amr's shoulder. At the end of the first day, the elephants of Sassanid army left the battlefield due to
Asim ibn Amr al-Tamimi's ploy, scaring away the alpha male of the elephant herd, which according to Tabari was identifiable by more brighter skin and being bigger than other elephants. The left flank of the Muslims also managed to stall the onslaught of Persian heavy cavalries. Amr was the one who instructed the Rashidun soldiers to sever the trunks of the elephants, which was done so by the soldiers around him, stopped the elephants' advance. Then Amr charged along with
Khalid ibn Urfuta, Jarir ibn Abdullah Al-Bajali, Al-Qaqa', Tulayha, Amr and
Dhiraar ibn al-Khattab to turn and engage against the
elephant corps, aiming their weapons to pierce the elephants' eyes, while also aiming to kill the elephant riders. According to an eyewitness of the third day battle, Amr announced he would cross the bridge alone to confront the enemy, instructing his followers to join him after a brief interval. Then they found Amr is fighting fiercely deep inside the enemy ranks; surrounded by the Sassanid soldiers, while his horse was incapacitated by enemy arrows. Regardless, when the Muslim soldiers managed to reach the encirclement of Amr, they found Amr was still alive and fighting alone inside the enemy ranks. During the fourth day of the battle of Qadisiyyah, Al-Qa`qa' devised a plan to end the fierce fighting against the Muslims and the Persians; he personally chose a group of some of the most valorous tribal chiefs from the Muslim army, such as Amr ibn Ma'adi Yakrib,
Al-Ash'ath ibn Qays, and Ibn Dhul-Bardain, for this mission. As the battle started, al-Qa'qa then executed the plan leading this special units that included Amr on a daring charge to penetrate the surprised Sasanian lines. The death of Rostam shocked the entire Sassanid army, which prompted Sa'ad to instruct general assault to all the Muslim soldiers, and ended the four day-long battles which resulted the annihilation of Sassanid main forces mustered in Qadisiyyah. During this battle, the Rashidun army had lost one of their most celebrated hero named
Abu Mihjan al-Thaqafi, whose death was witnessed by Amr. According to
Mohammed Hussein Heikal, Amr was rewarded a massive 2,000 Dirhams worth of spoils of war by Sa'ad for his astounding personal efforts in the battle of Qadisiyyah, although he did not earn bigger rewards, which were reserved for those who had memorized Qur'an, since Amr was not included as one of the
Hafiz.
Battle of Jalula Later, Amr participated in the
Battle of Jalula, where he was reported to have played an important role during this battle along with al-Qa'qa, Tulayha, Hijr ibn 'Adi, and Qays ibn Maksuh. According to Baladhuri, Amr was appointed as commander of
Rashidun cavalry during this battle. At night, Al-Qa'qa brought a number of elite cavalry to reach the door of the ditch. This act caused panic among the Sassanids as they began retreating, while the Rashidun forces noticed that al-Qa'qa and his units had penetrated and taken position on the trench behind the Sassanid army. One of the notable captives from this battle was the mother of Amr ibn Shurahil, a
Tabi'un hadith scholar. During the tenure of Sa'd ibn Abi Waqqas as governor in Kufa, there were scandalous accusations regarding Sa'd's unjust rule in Iraq, to which Umar responded by sending his agents to check and interview the populace in Kufa. Sa'd himself was called to Medina for interrogation. When Amr was interviewed, Amr testified in defence of Sa'd against the complaints and accusation of the Sa'd duty in Kufa, as according to Amr, the rule of Sa'd was "...just in law, caring the poors, humble in nature, and fair when giving rewards...". Mujashi also provided Amr with shields, swords, and another warfare equipment. However, their advance was halted due to the onset of winter, which prompted Ahnaf to ask whether they should continue or not, to which Amr replied that it was up to Ahnaf. Amr was then assigned by
Khalid ibn al-Walid to lead about 200 Rashidun cavalry to march towards
Harran Battle of Nahavand & Death , one of the last Sasanian strongholds during the Muslim conquest of Persia. On the eve of the
Battle of Nahāvand, the caliphate heard that the Sassanid armed forces from Mah,
Qom,
Hamadan,
Ray,
Isfahan,
Azerbaijan, and Nahavand had gathered in the area of Nahavand to counter the caliphate's invasion. Caliph Umar responded by assembling war councils to discuss the strategy to face the Sassanids in
Nahavand. As the battle plans has been set, at first the caliph wanted to lead the army himself, however, Ali urged the caliph to instead delegate the battlefield commands to the field commanders. Umar agreed, and decided to send Amr,
Zubayr ibn al-Awwam,
Tulayha,
Abdullah ibn Amr,
Al-Ash'ath ibn Qays and others under the command of
Al-Nu'man ibn Muqrin as reinforcements to Nahavand. As they arrived in Nahavand, Amr was sent as a scout to gather information about the enemy forces before the battle. Amr travelled for three days, exploring the fields around the area in Nahavand, to gather information regarding the enemy strength. The battle began with two days of intense skirmishing, as the Sassanid forces refused to leave their position within trenches despite their superior number, until the last day, as
Al-Nu'man ibn Muqrin asked the opinion of his commander how to break the Sassanid resistance. The Sassanids had entrenched themselves behind spiked ditches, and so Amr stated they should try to force a daring breakthrough manoeuvre against their lines to break the Sassanid resistances. Then, as the last day of the battle started, Tulayha's strategy was carried out, baiting the bulk of Sassanid forces to chase them as the Rashidun forces pretended to withdraw, while peppering the Sassanids with showers of arrows by their cavalry archers. Despite the overall victory, Amr was killed during this battle, along with his comrade Tulayha. Abu al-Farraj recorded that Amr was buried along with Nu'man, the Rashidun supreme commander who also fell during this battle. This has been considered dubious as the narrator chains were weak. According to Abu Hanifa, al-Farra account were ambiguously traced to untraceable source. == Personal characteristic ==
