So I said...
So I said: 'If he is a Prophet he will be informed, and if he is a king then we will have been relieved of him.' The Apostle of God overlooked her transgression. Then when she saw the conducts and morals of the Apostle of God she entered Islam and said: 'Now I know that you are a Prophet of God and I bear witness to you and who is with you that I will follow your religion.
I bear witness that there is no deity but God and that you, Muhammad, are the Apostle of God.' A Jew's Word was Enough The Apostle of God remained in Medina after his return from Khaybar until the month of Shawwal in the seventh year of the Hijrah. During this time he sent some sorties to consolidate the security of Medina and to warn those who still considered attacking the Muslims and also to deliver the message of Islam and explain its high-minded rules and teachings to them.
One such sortie was that of Osamah ibn Zaid. The Apostle of God sent him with some horsemen to a Jewish village said to be named al-Harqah to invite them to Islam. A Jewish man named Mardas ibn Nuheik approached the horsemen saying: 'Peace be upon you. I testify that there is no deity but God and that Muhammad is the Apostle of God.' But when Osamah ibn Zaid passed by him he speared Mardas and killed him.
When Osamah returned to the Apostle of God and told him of this the Prophet said: 'You killed a man who testified that there is no deity but God and that I am the Apostle of God?' Osamah said: 'O Apostle of God, he only said that to save himself from death.' The Apostle of God said: 'You did not lift the cover from his heart!
You neither accepted what his tongue was saying nor did you know what was in his mind!' In this regard God revealed: eAnd do not say to those who offer you a greeting of peace: you are not a believerf 140 Then the Apostle of God sent compensation to the family of Mardas ibn Nuheik. The Bearer of the White Banner The Apostle of God had sent al-Harith ibn 'Omeir al-Azdi with a letter to the king of Busra the absolute ruler of greater Syria in which he invited him to Islam.
When he stopped at Mu'tah the king's agent Sharhabil ibn 'Amr al-Ghasani arrested him and when he knew that he was the Prophet's messenger to the king he went against the prevailing customs of the time and killed him. No other messenger of the Apostle of God was killed despite the vast number he sent from Medina to kings and leaders after the treaty of Hodaybiyah.
