The enemy was assembled. After their efforts of the preceding day to extricate themselves from the briny mud of the "Sabkah," they had awakened with their throats afire; the storm, over too soon, not having filled any of the "ghadirs" and the wells of the Wadi having been choked up, the idolaters had not been able to find the least drop of water to allay the thirst that began to torture them. It was not to be wondered at, therefore, that the sight of the sheet of water sparkling in the reservoir dug by the Believers and which reflected the sun's rays, blinding their eyes, should increase the fury of their revengeful feelings. Some of the horsemen, reckoning on the speed of their steeds, dashed recklessly forward, hoping to reach the tempting liquid. The Prophet ordered his archers to let the mounted men get quite near, and when they were well within range, to riddle them with showers of arrows. All rolled on the ground, mortally wounded, with the exception of one rider, called Hakim. Al Asad al Makhzumi, another idolater, instead of being discouraged by the result of this first attempt, felt his blood boiling in his veins and shouted loudly enough to be heard by both parties: 'By our gods! by Lat and Uzza! I swear to slake my thirst in the cistern of Mohammad's "qawm." Then I'll demolish it and only death can stop me!' He dashed forward, brimming over with arrogance. Hamzah went to meet him and, with a blow from his scimitar, sliced off one of his legs and sent it flying. Al Asad fell backwards, turned himself over, and hopping with surprising agility on both hands and his sound leg, tried to make his way to the reservoir and keep his oath. But Hamzah was there to meet him and finished him off just as he reached the goal. Three champions came forward from among the ranks of the Unbelievers to challenge the Believers to single combat, and they were Utbah with his son, Al Walid, and his brother, Shaibah. Hamzah, Ali, and Obaidah were chosen by the Prophet to oppose them. Stalwart Hamzah and impetuous Ali soon rid themselves of their adversaries, stretching them bleeding and lifeless on the sand, but Obaidah and Utbah had no sooner crossed swords than they both wounded each other grievously. Obaidah, one leg so deeply gashed that the marrow dripped from the bone, was on his back, at his enemy's mercy, when Ali and Hamzah came to the rescue and freed him by killing Utbah. They then lifted up their wounded comrade and carried him to the Prophet, who supported his head lovingly on his knee, consoling him by the glad tidings of the reward awaiting him in Paradise. Obaidah soon breathed his last sigh and was thus the first martyr struck down in the Holy War.
