Hazrat Harith narrates that when we returned from Yemen and stayed in Madinah Munawwarah, Hazrat Umar (may Allah be pleased with him) came to us. He made a round among the people of the tribe of Nakha’ and said to them,“O people of Nakha’! I see honor descending among you. You should go to Iraq or Persia.”They said,“O Commander of the Faithful! We want to migrate towards Syria.”Hazrat Umar said,“No, Iraq is better. I am pleased with Iraq for you.”Some of us said,“O Commander of the Faithful! There is no hardship in religion.”Hazrat Umar said,“There is no hardship in religion; Iraq is suitable for you. There are groups of non-Arabs there and we are only two and a half thousand.”Then we came to Qadisiyyah, and from among the Nakha’i people only one man was martyred, while from the rest eighty people were killed. When Hazrat Umar found out, he said,“What did the Nakha’i people do that only one of them was martyred among the rest? Did the people run away leaving them?”The people replied,“No, rather they themselves jumped into the difficult tasks willingly.”

Hazrat Harith narrates that Hazrat Umar (may Allah be pleased with him) passed by the people of Nakh‘a and counted them; they were two and a half thousand. Their leader’s name was Arta’ah. Hazrat Umar said: I see honor descending among you; go to your brothers in Iraq. They said: No, we will go to Syria. Hazrat Umar said: Go to Iraq. They said: There is no compulsion in religion. Hazrat Umar said: Go to Iraq. So they went to Iraq, and there they began to capture and slaughter foals. Hazrat Umar wrote them a letter: Set yourselves right, for in such matters, life is important.

Hazrat Abu Bakr bin Ayyash states that in the Battle of Qadisiyyah, there were four hundred from Banu Asad, three thousand from Bajilah, two thousand three hundred from Nakhai, and the same number from Kinda. All these people totaled ten thousand, and among the people, there was none less than the tribe of Mudar.

Hazrat Abu Bakr says that Hazrat Umar gave more to some—two thousand to some and six hundred to others.

Hazrat Abu Bakr bin Ayyash, in the commentary of the verse { فَسَوْفَ یَأْتِی اللَّہُ بِقَوْمٍ یُحِبُّہُمْ وَیُحِبُّونَہُ } of the Holy Qur'an, says that it refers to the people of Qadisiyyah.

Hazrat Abu Bakr bin Amr bin Utbah narrates that Hazrat Umar wrote a letter to Hazrat Sa’d and the other governors of Kufa, saying: The region between ‘Udhaib and Hulwan has come under my authority. This is sufficient for you if you adopt piety and act righteously. And maintain a distance between yourselves and your enemies.

Hazrat Awn bin Abdullah narrates that in the Battle of Qadisiyyah, the belly of a Muslim warrior was torn open and his intestines had come out. He said to a person passing by him, "Put my intestines back inside and make me walk so that I can advance a little further in the path of Allah." So that man did as he was asked.

Hazrat Abu Ishaq says that I saw the companions of Ubaid drinking nabidh of Qadisiyyah, and among them was Amr bin Maymoon as well.

Hazrat Mutarrif narrates that Hazrat Talha bin Ubaidullah bought a piece of land from the people of Sailhin in Kufa. Then he came to Hazrat Umar and mentioned it to him and said that he had bought a fine and beautiful piece of land. Hazrat Umar asked, "From whom did you buy it? From the people of Kufa? Did you buy it from the people of Qadisiyyah?" Hazrat Talha said, "I bought it from all the people of Qadisiyyah." Hazrat Umar said, "You have done nothing; this is spoils of war."

Hazrat Laith says that the warriors of Qadisiyyah invited the non-Arabs to battle and fought with them for three days.
