And then I realized that the thin and tall youth he gazed at was Abu Huzayfa-his son. Like Abu Sufyan’s daughter Ramla, Utbah’s son Abu Huzayfa had defected to the Muslims, adding to the enmity between Muhammad and the tribal chiefs, who accused him of seducing their children with sorcery. I saw the troubled look on my husband’s face as he saw father and son stare at each from across the battle lines, and I realized that the Messenger would never have allowed Abu Huzayfa to come with the raiding party had he known this would be the outcome.

But then Utbah regained his composure, a mask of iron covering his raging emotions. He waved his sword defiantly and issued the ancient words of challenge.

“Muhammad! Here stand the lions of Quraysh,” Utbah said. “Send forth worthy men to face us-or surrender in shame.”

To my horror, I saw Abu Huzayfa unsheathe his sword and move forward, ready to duel his own father to the death. And then Hamza caught the stern look on my husband’s face and he put a restraining arm on the boy’s shoulder.

“No. Not you.”

Abu Huzayfa stepped back and his own mask of defiance fell, and I saw in his eyes terrible grief.

And then I felt a rustle of movement beside me as the Prophet rose and chose the champions who would defend the Muslims. He gazed at the eager faces of his warriors, and then made a decision that I knew was tearing his heart in two. The best men to face Utbah’s challenge were those who shared his own blood. He pointed to three of his most beloved family members-his cousin Ubayda ibn Harith, his uncle Hamza, and Ali, the boy he treated like a son. I felt tears burning my eyes. I could not imagine how hard it was to send the people he loved the most to face the possibility of death before his very eyes.

The three chosen ones of the Ahl-al-Bayt, the House of the Prophet, stepped forward proudly onto the field, facing their opponents. Hamza had tossed aside his bow for a broadsword, and Ubayda held aloft a saber with a jewel-encrusted hilt that shimmered in his hands.

And then Ali unsheathed his sword and I heard a gasp and realized with some surprise that it was my own. He held in his hand a blade unlike any I had ever seen. Two blades actually, for the sword split in half as it tapered to the point, making it look like a forked serpent’s tongue. The hilt was made of polished silver, and gold filigree was etched onto the dual blades, which had a black sheen that suggested they were forged not from steel but from some other metal I had never encountered. I would later learn that this sword was called Dhul Fiqar and belonged to the Messenger himself. Whenever I asked him in later years where he had acquired such an unusual and magnificent blade, he merely smiled and changed the subject.

Ali flicked his wrist and Dhul Fiqar cut through the air, making a strange singing sound that added to its mystery. He moved forward to face his opponents, and I saw his eye fall on Waleed-one of the men who had tried to assassinate the Prophet the night he escaped Mecca. There was a strange look between them, and I remembered what Ali had said of that night and the promise he had made to Waleed that the next time they would meet, the brother of Hind would die.

A shadow fell over the battlefield and I looked up to see that a heavy cloud blanketed the sun. Which was peculiar, as the sky had been absolutely clear only moments before.

There was a moment of terrible silence, as if history itself were holding its breath. And then, with a cry of fury, Utbah rushed at the men who had answered his challenge. Ubayda moved to intercept him and their swords met with a terrifying crash. And then Hamza was upon Shaybah and Ali faced young Waleed.

Sparks flew as the three men struck at one another, and there was a terrifying beauty to their dance. Despite his age and bulk, Hamza spun and parried like a youth, and Ubayda struck at Utbah’s sword with such fury that I was surprised it did not shatter under the blows.

My eyes flew to Ali, who seemed to be moving at a different speed from the others. It was as if time around him slowed; his sword movements were elegant and beautiful, like those of a fish swimming in a gentle stream. Waleed looked confused as he met Ali’s attack, as if he also sensed something was different about his opponent. I saw the looks of consternation from men on both sides of the divide as Ali fought from inside the strange dreamworld that he alone seemed to inhabit.

And then I thought the sun must have emerged from behind the cloud, as Dhul Fiqar began to sparkle and glow, the blade shining brightly as if it were a torch in Ali’s hand. But I soon realized with some shock that the field was still covered in shadow and I could not account for the strange light that was emanating from the sword.

Waleed saw it, too, and his mouth fell open in shock. And at that moment, Ali raised the sword and, with the grace of an eagle racing toward its prey, he ran the blade through Waleed’s neck. The young man’s head fell cleanly off its shoulders with one stroke and blood erupted like a volcano from the severed neck. Waleed’s headless body stood frozen as if in disbelief and then fell to the side.

Ali’s prophecy had at last come true.

I heard a soft moan and saw that Abu Huzayfa was struggling to keep his composure at the sight of his brother’s decapitation. And then the cloud that had unexpectedly covered the sun evaporated just as mysteriously, and the field was burning with light again. I saw Utbah’s face go white as he saw his son’s head lying only a few feet away from him, and then, with the terrible cry of a man who no longer wished to live, he threw himself at Ubayda.

An instant later I saw Hamza slash down onto Shaybah’s shoulder. Hamza’s broadsword tore through muscle and bone until Shaybah’s sword arm was ripped away, and the champion of Quraysh died in a flood of blood and convulsions.

Utbah now stood alone against three men, and yet he continued to fight as if he were supported by an army. There was a madness in his eyes that gave him a ferocity I have never seen before on any battlefield. The Prophet’s cousin Ubayda fell back under Utbah’s furious blows and then suddenly made a swift kick with his leg, catching the Meccan chieftain behind the ankle. Utbah stumbled and fell.

But as he did so, he swung his ugly sword and cut off Ubayda’s leg above his knee. Ubayda screamed in agony as a river of gore erupted from his stump, and I heard a terrible sound of grief erupt from Muhammad’s throat.

Utbah managed to get to his feet and moved toward Ubayda, ready to deliver the deathblow. He raised his sword high…and Ali threw Dhul Fiqar across the battlefield. It spun in the air like a disk, flying with perfect precision, until the double blades connected with Utbah’s sword arm and severed his wrist.

Utbah did not cry out, did not appear to feel any pain. He stood weaponless and alone, his eyes glistening as he stared at the headless body of his beloved son. And then Hamza was upon him and the mighty broadsword tore through Utbah’s rib cage and emerged from his back, like a knife cutting through a milk curd.

Utbah stood there, impaled through the heart. I saw him gaze across the field to his surviving son, his traitorous boy who had chosen Muhammad over him. Abu Huzayfa’s face was frozen in horror as he met his dying father’s gaze.

And then Utbah did something that I will never forget or perhaps understand. He smiled at Abu Huzayfa and nodded, as if he were proud of him. With a final shudder, the father of Hind fell to his knees and returned to the God he had denied.

Silence reigned over the battlefield as the horrified Meccans dispatched sentries to recover the bodies of their slain champions. Hamza and Ali lifted Ubayda, who was swimming in a pool of his own blood but somehow managed to live. They carried their kinsman to the Messenger’s command post, resting his head in my husband’s lap. My father immediately knelt down and tried to bandage the stump and cut off the bleeding, but we all knew that Ubayda had lost too much blood for Abu Bakr’s efforts to matter.
