After the battle of Nihawand, many Persians, men, women, and children were taken as captives by the Muslims. The captives were sold as slaves. One of these slaves was Firoz alias Abu Lulu. He was purchased by Mughirah Shu’bah the Governor of Basra. This Firoz was a craftsman, a carpenter, an iron smith and a painter. Umar did not allow non-Muslim adult captives to reside in Madina. Mughirah sought special permission for the residence of Firoz in Madina on the ground that as he was a skilled craftsman, he would be of service to the people. Umar gave the permission as a special case.
One day, Firoz waited on Umar and complained that the tax which his master Mughirah was exacting from him was too high. He wanted the Caliph to reduce the levy. Umar enquired what work did he do. He said that he worked as a carpenter, painter, and an ironsmith. He added that he could make windmills as well. Umar next enquired as to the amount of the tax that he was required to pay to his master. He said that he had to pay two dirhams a day. Umar said that keeping in view the lucrative nature of the jobs done by him, the levy of two dirhams a day was prima facie not excessive. Umar said that he would, however, write to Mughirah, and examine the question further in the light of what Mughirah said. That did not satisfy Firoz, and he went away sulking.
Umar wrote to Mughirah, and in reply Mughirah quoted facts and figures to establish that what he took from his slave was by no means excessive. When Firoz called on Umar again, Umar explained to him that as the levy was not excessive, no reduction therein was called for that made Firoz angry. In order to humor Firoz, Umar said, “I understand you make windmills; make one for me as well.” In a sullen mood, Firoz said, “Verily I will make such a mill for you, that the world would talk about it.” As Firoz went away, the Caliph told the people around him that the Persian slave had threatened him.
There were Persian children slaves in Madina. Seeing them, Firoz would say, “You have been enslaved at such a tender age. This Umar sees eaten my heart. I will take his heart out”. He made for himself a dagger with a very sharp edge and smeared it with poison.
On the 1st of November 644 A.D. at the time of the morning prayer, Firoz went with his dagger to the Prophet’s mosque and hid himself in a corner in one of the recesses of the mosque. When the faithful stood for prayer after straightening the lines, and Umar took up his position as the Imam to lead the prayer, Firoz emerged from his place of hiding and rushed at Umar. Firoz struck Umar six consecutive blows with his dagger, and Umar fell on the floor profusely bleeding.
Other persons rushed at Firoz, but he had the fury and frenzy of a desperate man about him. He struck right and left, and thirteen Muslims were wounded, some of them fatally, before Firoz could be overpowered. At last realizing that he could not escape, Firoz stabbed himself to death with his own dagger.
Umar On Death Bed
From the mosque Umar was carried home. When he regained consciousness he asked who was his murderer. He was told that his murderer was the Persian slave Firoz. Thereupon Umar said, “Praise be to God that I have not been murdered by a Muslim”.
The physician administered him date cordial and milk. These could not be digested and gushed out of his wounds. That indicated that the wounds were fatal and that he could not survive for long.
The people around him praised him for his virtues and sterling qualities. He asked them not to praise him. He said:
“All praise is to Allah. If all the treasures of this world were to be at my disposal, I would offer them as a ransom to be saved from the trial at the Day of Judgment.”
He then recited the Arabic verse:
“I have been unjust to my soul,
Except that I am a Muslim,
Say my prayers and fast.”
Umar asked his son Abdullah to wait on Ayesha and beg her permission for his burial by the side of the Holy Prophet and Abu Bakr. Ayesha wept as she came to know that Umar was about to die. She said, “I had reserved this place for my own burial, but I give Umar precedence over myself. Let him be buried there”. When Umar was told that Ayesha had given the permission, he felt happy and said, “God bless Ayesha. She has fulfilled my greatest wish. Now I can die in peace.”
Then he asked his son to estimate the debt that he had to pay. He was told that the debt amounted to eighty six thousand dirhams. This included the salary that he had drawn from the Baitul Mal during the period of his caliphate. He instructed that the debt should be paid by the sale of his property. Thereafter Umar gave detailed instructions to his son regarding his funeral. He said:
“Be moderate in the expenses of my shroud, for verily if there is anything of good with God in my favor, He will give me in exchange what is better than it, and if I have been otherwise, He will strip me of all that I have. And be moderate in the grave that you dig for me, for verily if there be anything of good with God in my favor, He will widen it for me, and if I have been otherwise, He will make it narrow for me to squeeze my body. And let no woman go with my funeral. Praise me not for that which is not in me, for the Lord knows best what I am. Therefore when you carry me to the grave, hasten in your going for if there is anything of good with God in my favor you will speed me to that which is good, and if I have been otherwise, you will cast from your necks an evil that you bear.”
Thereafter Umar turned his face to the Qibla and breathed his last. There was serene smile on his face as he lay dead.
