Saif narrated from another source that a soldier said, “We swam in the river and the deepest water was up to the horse's belly whenever a horseman stopped for a rest.” In other places Saif says that all crossed the river, with the exception of a man called Gharqadah (meaning drowned) who fell off his horse. The narrator says that it seems that he saw his horse shaking water off his mane and the man floating. Qa‘qa‘ pulled him to the shore and saved him.
After he was saved Qa‘qa‘'s mother said to Qa‘qa‘, “No sister has given birth to a hero like you.” Abu Na‘eem has mentioned some parts of the above history in his book The Signs of the Apostleship, and counted them as evidence of the prophethood of the Prophet of Islam. Origin of Saif's story Saif has recorded from Muhammad, Talha, Mohallab, Nazr Bin Rofail, and an unknown man. Some of these narrators we have mentioned before.
Tabari has recorded sixty-seven stories of Saif from Mohallab, Ibn ‘Oqbah Asadi, and twenty-four stories of Saif from Bin Rofail. No trace of these narrators can be found in any biography book. Saif's stories by un-named men are obvious that are unreal. Battle of Madaen according to others apart from Saif. Hamawi in vol.4, p.333, Mo‘jamol-Boldan says: "The Persian Farmers helped the Muslim army by showing them the Persian weak points, giving them presents and provisions.
Khalid Bin ‘Arfata attacked Persians unsuccessfully. Later Khalid conquered Madaen. The Muslim army was guided to shallow parts of the river so they crossed there." In Fotoohol-Boldan, page 323 says: "Persian army fired arrows at the Muslims, but not one was killed except a soldier from the Tay tribe called Salil Bin Yazid Bin Malik Sinbesy." Conclusion Saif made ‘Asem from his own tribe, though fictitious, the hero of the story.
He also said, "Any horse that tired, a hill appeared under its feet." But a man fell off his horse, and the seabed did not rise up under his feet, because Qa‘qa‘ the brother of ‘Asem was in the vicinity to save him. The soldiers crossed the river by a miracle, according to Saif. But according to others a guide showed them a fording place, a shallow strip or a strip of land. The biggest damage done by Saif to the history of Islam is his invention of Sahabis (companions of the Prophet).
He has mentioned their names in fictitious and real events, distorted in one way or another.
