Battle of Yarmuk [Hazrat Musleh Mau'd's (ra) Narration]
With regard to the Battle of Yarmuk, with particular focus on its conclusion, Hazrat Musleh Maud (ra) writes:
“When the battle finished, the Muslims went in search of Ikrimah (ra) and those with him [who launched the attack]. They discovered that 12 of them were severely injured including Ikrimah (ra). Upon seeing the grave condition of Ikrimah (ra), one of the Muslim soldier said to him, ‘O Ikrimah (ra)! I have a water bag with me, drink some water from it.’ Ikrimah (ra) turned his head and saw that Hazrat Fazl (ra), the son of Hazrat Abbas (ra), was lying injured near to him. Ikrimah (ra) said to the Muslim soldier, ‘My honour would not permit me to quench my thirst and live, whilst those people and their progeny, who assisted the Holy Prophet (sa) at a time when I was his staunch enemy to die of thirst.’” He was invigorated with a new passion to sacrifice for others; “‘Therefore first give the water to him (i.e. Hazrat Fazl bin Abbas (ra)). If there is any left, then bring it for me.’
“The Muslim soldier then went to Hazrat Fazl (ra), but he indicated that another injured Muslim ought to be given water first, as he was more in need than he was. The Muslim soldier then went to him, but he also stated that another injured Muslim was more in need of water, therefore he ought to go to him first. Accordingly, whichever injured soldier he would go to, they would send him to the next person and none would drink the water. When the Muslim soldier went to the last of the injured soldiers, he had already passed away. He then went to the next injured soldier and eventually returned back to Ikrimah (ra), but by then they all had passed away.”
