Khawarij Revolts, Marwan’s Defeat, and the Fall of Umayyad Caliphate

Khawarij

A brief of the situation in Khorasan has been given above. We will now discuss the Khawarij factor. They observed the civil wars and weaknesses in Islamic territories and used these situations to assist them in their revolt. The Khawarij of Khorasan chose Dhahak bin Qais Shebani as their leader. Dhahak attacked Kufa and occupied it and Abdullah bin Umar bin Abdul Aziz had to retreat from Kufa and go to Wasit. Sulaiman bin Hisham, defeated by Marwan bin Mohammad, joined Dhahak bin Qais. That of course added to Dhahak's overall strength. Dhahak then invaded Mosil. There Marwan bin Mohammad’s son, Abdullah bin Marwan, faced him with only 7000 soldiers while Dhahak had one hundred thousand fighters, and with this army he surrounded Abdullah bin Marwan. Marwan, Abdullah's father received this information and turned his attention to his son's predicament. After a fierce battle, Dhahak was killed and the Khawarij chose Sayeed bin Bahdal as their leader but he was also killed. Then they made Sheban bin Abdul Aziz their new leader. Marwan sent Yazid bin Hubaira towards Kufa. He went there and turned out all the Khawarij from that city. On the other side, Sheban bin Abdul Aziz, taking all the Khawarij with him, went towards Iran. There he joined Abu Muslim as has been mentioned above and was killed in 130 A.H. The Hijaz, Yemen and Hadramawt (ancient South Arabian kingdom that occupied what are now southern and southeastern Yemen and part of the present-day Sultanate of Oman) also saw rebellions and Abu Hamza Mukhtar bin Auf Azdi raised the flag of rebellion and Abdullah bin Yahya, the ruler of Hadramawt joined him. Abu Hamza first captured Madinah and then moved towards Syria, Marwan bin Mohammad deputed Ibn Atya Sadi to confront him and they met at Wadi Qura. Abu Hamza was killed in the battle. Ibn Atya then proceeded to Yemen and confronted Abdullah bin Yahya who was ready to face him a battle ensued and it resulted in Abdullah bin Yahya's death. Ibn Atya cut off his head and sent it to Marwan. At the time Marwan bin Mohammad was at war with Dhahak Khwarji near Mosil, a letter written by Imam Ibrahim and addressed to Abu Muslim Khorasani was intercepted and given to Marwan. It contained instructions that included, "Don't spare even a single Arab or a descendent of an Arab. The natives of Khorasan who have embraced Islam will stand us in good stead. We should rely on them more". The letter also revealed that Banu Abbas had spread the net of conspiracy against Banu Umayyah for quite a long time and Imam Ibrahim whose center of operations was at Hamima in Balqa was the engineer of these plots.

Marwan bin Mohammad after reading the letter ordered his ruler in Balqa to arrest Imam Ibrahim and send him to the caliph. So, Imam Ibrahim bin Mohammad along with several members of his family was caught and sent to caliph Marwan as captives. They were put in jail at Harran. Along with Imam Ibrahim Sayeed bin Hisham bin Abdul Malik and his two sons, Uthman and Marwan, Abbas bin Waleed bin Abdul Malik, Abdullah bin Umar bin Abdul Aziz and Abu Muhammad Sufyani were also imprisoned. In a matter of days an epidemic broke out in Harran and Imam Ibrahim, Abbas bin Waleed and Abdullah bin Umar bin Abdul Aziz died from the disease.

Sayeed bin Hisham along with the other prisoners killed the jailer, broke open the jail door and escaped. The inhabitants of Harran caught the escaping prisoners and killed them. Abu Mohammed Sufyani did not escape from jail with the others. He was released by Marwan bin Mohammad after he returned defeated from Zab river battle. Imam Ibrahim left his will at the time of his arrest and imprisonment that after his death his brother Abdullah bin Mohammad, popularly known as Abus Abbas Saffah would be his successor. He also willed that Abul Abbas Saffah should not stay in Balqa but in Kufa. Imam Ibrahim, before his arrest, had directed that Abu Muslim Khorasani should be as their officer to comply with this order and then Imam Ibrahim sent Qahtaba bin Shabeeb to Abu Muslim with a black flag to revolt and capture Khorasan. Abdullah bin Mohammad Saffah along with his family settled in Kufa in accordance with the will of his brother.

Abu Muslim brought under his control the whole of Khorasan between 130 A.H. and 131 A.H. Then he sent Qahtaba bin Shabeeb with an army towards Kufa. Kufa was captured and then the oath at the hand of Abul Abbas Saffah Abdullah bin Mohammad followed. Upon receiving this news Marwan bin Mohammad left Harran with 120,000 warriors and marched towards Kufa. The confrontation between his army and Saffah's army under the command of his uncle Abdullah bin Ali took place adjacent to the Zab River. If Marwan bin Mohammad's army had the desire to fight, it could have easily defeated Abul Abbas Saffah's army. However in the midst of the battle at the point that Marwan had forced the greater portion of Abdullah bin Ali’s army into retreat and there was no doubt left that Marwan would be victorious, the greater portion of Marwan's army refused to attack and continue the fight as if their purpose was to cause his defeat.

Abdullah bin Ali, finding himself on the verge of defeat and deciding to risk everything, attacked with a selected group of men. None of Marwan's leaders came forward to meet this last desperate challenge. Marwan tempted them with rewards and special favors but without response. Then he poured all his treasure on to the battlefield and told them to attack and after killing the weakened enemies, they could distribute it among themselves. The army failed to follow his orders and became engrossed in looting the exposed valuables and even those few who were still fighting left the battle and also began looting. Shocked at this disorder and chaos Marwan sent his son, Abdullah to stop the looting. As soon he reached where they were looting the treasure, they began to flee and left Marwan with only a few persons. Marwan was disillusioned with the disloyalty and disobedience of his army and escaped. He arrived in Mousil where the people taunted him for his defeat. He realized the futility of staying there and went to Harran where his nephew Abbas bin Yazid bin Mohammad was the Governor. Marwan was defeated on Saturday 11 Jamad-al-Thani 132 A.H. along side of the Zab River. He had stayed at Harran for 20 days when he heard of Abdullah bin Ali’s approach and he immediately left for Hims. When Abdullah bin Ali reached Harran, its Governor Abbas came out in black clothes and holding a black flag to receive him and took the oath for Saffah’s caliphate at his hands. Abdullah bin Ali granted him pardon. When Marwan reached Hims, the citizens at first showed their obedience and respect but when they realized his military weakness, they prepared to revolt and fight him. Marwan left Hims after three days. The citizens of Hims wanted to rob him of his valuables. Marwan first tried to argue with them and make them see reason but they did not give up their attempts to overpower him and he fought with them and made them withdraw.

From Hims Marwan went to Damascus. Its governor was his cousin Waleed bin Muawiya bin Marwan bin Hakarn. He did not stay there he only induced the governor to fight against the opponents of Banu Umayyah, he went to Palestine and stayed there hoping to lead a life of silence and retirement.

In Harran Abdullah bin Ali, after pulling down the jail where Ibrahim bin Mohammad had been in captivity, moved towards Damascus. On the way his brother Abdus Samad bin Ali whom Saffah had sent to help him with a body of 8000 soldiers, arrived. Then he, after taking the oath from the people of Harran, went to Damascus via Qansareen and Balbak and laid siege to it. After a short siege he entered Damascus on Wednesday 5 Ramadan 132 A.H. by force and blood flowed in its streets.

Its governor Waleed bin Muawiya was killed in the confrontation. After the massacre and victory Abdullah bin Ali stayed there for 15 days and then went to Palestine. He had just arrived at the Palestine border when he received a letter from Abdullah bin Saffah asking him to send his brother Saleh bin Ali in pursuit of Marwan. Marwan left Palestine and went to Arish (town in the northeastern section of the Sinai Peninsula), then to the Nile River and then to Said. Saleh continued the pursuit and camped at Fustat (this was the earliest Arab settlement in Egypt south of modern Cairo) from there he sent a division of his army in search of Marwan. By chance, Saleh’s soldiers came across Marwan's cavalry.

Marwan’s horsemen were already in low spirits and frustrated they did not fight and fled away and a few of them were also captured. When they were interrogated, they revealed Marwan's location, informing them that he was at Boseer. The officer of Saleh's division Abu Aun thought it best to launch a night attack on Marwan for he knew that to face him would not be easy and they attacked as planned. Surprised at the sudden attack, Marwan came out of his house. A soldier was laying in wait for him attacked him with a spear. He fell down and one of his men said, "The Amir al-Muminin is dead." Hearing it Abu Aun and his men rushed to him and cut off his head and sent it to Abul Abbas Abdullah Saffah.

This occurred on 28 Dhul Hijjah 132 A.H. corresponding to 5 August 750 AD and with it came to end the Caliphate of Banu Umayyah and began the Caliphate of Banu Abbas. Following Marwan's death his sons Abdullah and Obaidullah, fled to Ethiopia. The Africans did not grant them safe passage and they killed Obaidullah and Abdullah escaped to Palestine and began to live there in hiding. During the Caliphate of Mahdi, the governor of Palestine arrested him and sent him to the court of Mahdi and he put him into prison.
