In the year 965 CE, al-Mutanabbi was riding home from the court of Adud al-Dawla al-Buwayhi in Shiraz to Baghdad. He was fifty years old. He had spent a lifetime writing poetry that made him the highest-paid poet at every court he attended. He had praised the Hamdanid Sayf al-Dawla of Aleppo in odes that are still memorized by Arab schoolchildren today. He had mocked the eunuch Kafur of Egypt so cuttingly that the mockery became a permanent scar on Kafur's reputation. He had bragged in his own poems that he was greater than every poet before him.
One of his most famous couplets ran:
*The horse, the night, and the desert know me, And the sword, and the spear, and the paper, and the pen.*
The couplet had become one of the signatures of his poetry. Every Arab who could read had memorized it. It was a boast, but it was also a claim about identity. Al-Mutanabbi was saying: my life is inseparable from combat and from writing. I am known by the tools of the warrior and the tools of the writer, together.
He was riding home. His son was with him. His servant was with him. He had gold from Adud al-Dawla in his saddlebags.
Near the village of Deir al-Aqul, southwest of Baghdad, a group of bandits ambushed the small party. The bandits were led by a man named Fatik al-Asadi, who had a personal grudge against al-Mutanabbi. Al-Mutanabbi had earlier written some cutting lines about Fatik's tribe.
Al-Mutanabbi saw the ambush. He estimated the odds. There were many bandits. He was outnumbered. His son and servant were with him. He turned his horse to flee. In the language of pre-Islamic Arab warfare, he was doing what any reasonable man would do: retreat, save the horses and the gold, live to fight another day.
His servant caught the bridle. The servant said: al-Mutanabbi. Al-Mutanabbi looked at him. The servant said: are you not the one who wrote:
*The horse, the night, and the desert know me, And the sword, and the spear, and the paper, and the pen.*
Al-Mutanabbi stopped.
The couplet contained his own claim. He was the man of the horse and the sword. Every Arab who knew the couplet also knew what it required of the man who had written it. To flee from bandits was to unravel the couplet. To fight was to keep it.
He turned his horse. He drew his sword. He said, according to the account preserved by his early biographers: you have killed me, servant.
He rode into the bandits. He was killed in a few minutes. His son was killed with him. The bandits took the gold, the horses, and the manuscript of his last poems, which he had been carrying with him.
The manuscript was later recovered. His diwan, three hundred and some poems, was compiled by his students. It became one of the four founding corpuses of classical Arabic poetry, alongside those of al-Buhturi, Abu Tammam, and al-Ma'arri. His couplets have been memorized, in every generation since, by every serious student of Arabic.
The lines quoted in his own death continue to be recited today. They are quoted with a knowing smile at the mention of what they cost him. Arab schoolchildren memorize them, and their teacher tells them the story of Deir al-Aqul. The lesson every teacher draws is the same: al-Mutanabbi was killed by his own line, not by his enemies. His own words held him to a standard. He could have died by an enemy's spear. He would rather die by his own couplet.
What the story teaches. A poet writes lines. The lines outlive the poet. But sometimes the lines outrun the poet in his own lifetime. Al-Mutanabbi had made a claim in a couplet. He was the man of the horse and the sword. He was known by them. When the moment came to escape by leaving those tools behind, his servant asked him: are you not the man of the horse and the sword? Al-Mutanabbi could not step out of his own line. He fought and he died. A serious writer accepts that the words they set down publicly are a covenant with their own future. Al-Mutanabbi kept the covenant. He kept it in the only way that made the couplet true. The lesson is that language, at its most serious, is not description. It is commitment.
