As Ibn Khaldun said in his introduction: (The art of history is one of the arts that nations and generations circulate, and that rides and men are pulled to it, and it transcends to its knowledge, the marketplace and the anfal, and the kings and the heavyweights compete in it, Scholars and ignorant people are equal in his understanding, since in his appearance he is no more than news about days and states.) History is a study of accidents, whether they are big or small, so reading the days and wars of the Arabs in the pre-Islamic period and Islam is a major source for knowing the days and history of the Arabs.

One of the most famous days of the Arabs was the Al-Basous War, that war that took place during the pre-Islamic era and lasted for forty years. The war took place between Bakr and the victory of the two sons of Wael bin Hanab bin Afsa bin Jadila bin Asad bin Rabia bin Nizar bin Maad bin Adnan. The war was due to the killing of Kulaib, and his name was Wael bin Rabia bin Al-Harith bin Zuhair bin Jashem bin Bakr bin Habib bin Amr bin Ghannam bin Taghlib. He yells and howls, and no one hears his howl except to avoid him, and he does not come close to him, and he was called Clip Wael.

He was the brigade of Rabia bin Nizar the Great, and the brigade was in Anza bin Asad bin Rabi`ah, and it was among their Sunnah that they grow their beards and cut their moustaches, and whoever does that from Rabi`ah does not want to fight them, then the brigade turned in Abdul Qais and it was in their Sunnah, if they insulted they were slapped by He cursed them, and if they hit, they killed those who slapped them. Then the brigade turned to Al-Nimr bin Qasit bin Hanab, and they had no more than a year of their advance. Then the brigade turned to Bakr bin Wael, then the brigade turned to Taghlib.

The war took place between two tribes, overpowered, represented by Al-Zir Al-Salem, Al-Malik Kulaib bin Rabi’ah, and the Bakr tribe represented by Jasas bin Murra. For the Arabs, he was an unfair and strong personality, so if he went out to a fever and was surfing the camels, he saw the she-camel of Al-Jarmi and threw her udder and poured it until it was blessed in the yard of its owner.

Al-Basous heard her neighbor’s screams, so she went out to him, so she screamed and humiliated him, and Jassas was seeing her and said to her: “Shut up and don’t take heed, and the Jarami lived and said to them: I will kill a camel greater than this she-camel. So he killed him, and that was the beginning of the spark of the war, and Jassas ordered a man who was with him called, Amr bin Al-Harith bin Dhul to make stones on him, so that the wolves would not eat him, and he says in that Mohalhal bin Rabia, the brother of Kulaib: A dead man, Amr and Jassas bin Murrah Dhi Sarim, hit his heart. I am deaf, and he did not sympathize there with intimate matters, for tomorrow and the day after tomorrow there will be a pledge of what will be held, a great curse, a grave thing that I cried with a clip.

Then Jassas rode his horse, after killing Clip, he rode his horse. When his father saw him, he said: Jassas came to you with an intuition, and said to his father, You have been stabbed. For your bereaved mother, he said, You killed Kulaib. Hammam was the brother of Jassas, and Muhalhal, the brother of Kulaib, at that time gathered for a drink. So Jassas sent a maidservant to tell him, and Hammam said to Muhalhal, ‘Drink, for today is wine, and tomorrow is an order,’ and Hammam came out after a sluggish drunk, and they went to Kulaib and buried him, after which they revolted. The tribe of Taghlib for the killing of Kulaib began to fight the Bakr tribe until avenging the death of its king and led the war, Al-Muhalhal bin Rabia.

On the day of Unayzah: The first fight between them was at Falaj, and they met with a water called An-Nah. Banu Shayban was descending on it. The chief of Taghlib was Al-Muhalhal, and the chief of Shayban was Al-Harith bin Murra. The district was Lubna Taghlib, and Al-Shoka was in Banu Shayban, and on that day no one from Banu Murrah was killed.
The Day of Al-Dhahabi: They met with the Dha’ib, and that was the greatest incident between them. Banu Taghlib won and on this day Sharaheel bin Murra bin Hammam bin Dhuhl bin Shayban was killed, Al-Harith bin Murra was killed, and the Banu Dahl bin Thalabah Amr bin Sudus bin Shaiban and other Bakr chiefs were killed.

The day of Wardat: So they fought a fierce battle, and the battle was victorious too, and the fighting increased in Bakr, so Hammam bin Murra was killed, and Jasas’s brother was astonished by his father and mother.
Yum Uwayradat, Yum Aniq, Yum Dhariya, Yum al-Qusaybat, and Yum al-Taqlib was also victorious.
On the day of the landslide: or on the day of the faction, the tribes of Taghlib fled and Al-Muhalhal fled and separated from his people and camped in Bani Janab. The war ended and after these facts the Taghlib tribe dispersed and migrated to the Euphrates Island, northwest of Iraq, which was called the home of Rabi’a.
