He said, `Well, this man has offered you a reasonable proposal, it is better for you to accept it and allow me to meet him.' They said, `You may meet him.' So, he went to the Prophet and started talking to him. The Prophet said the same to him as he had to Budayl bin Warqa.
Then `Urwah said, `O Muhammad! Won't you feel any qualms by exterminating your relations Have you ever heard of anyone among the Arabs annihilating his relatives before you On the other hand, if the reverse should happen, by Allah, I do not see dignified people here, but people from various tribes who would run away leaving you alone.'
Hearing that, Abu Bakr verbally abused him and said, `Go suck Al-Lat's clitoris! Are you saying we would run and leave the Prophet alone' `Urwah said, `Who is that man'
They said, `He is Abu Bakr.' `Urwah said to Abu Bakr, `By Him in Whose Hands my life is, were it not for the favor which you did to me and which I did not compensate, I would rebuke you.' [Abu Bakr had given 'Urwah 10 camels as a favour before Islam.]
`Urwah kept on talking to the Prophet and seizing the Prophet's beard as he was talking, while Al-Mughirah bin Shu`bah (a nephew of 'Urwah) was standing near the head of the Prophet , holding a sword and wearing a helmet. Whenever `Urwah stretched his hand towards the beard of the Prophet , Al-Mughirah would hit his hand with the handle of the sword and say, `Remove your hand from the beard of Allah's Messenger.'
`Urwah raised his head and asked, `Who is that' The people said, `He is Al-Mughirah bin Shu`bah.' `Urwah said, `O treacherous (one)! Am I not doing my best to prevent evil consequences of your treachery' Before embracing Islam, Al-Mughirah was in the company of some people. He killed them, took their property and came (to Al-Madinah) to embrace Islam ['Urwah was the relative of Al-Mughirah so 'Urwah had to pay the blood money for the people Al-Mughirah killed before becoming Muslim].
The Prophet said to him,
«أَمَّا الْإِسْلَامُ فَأَقْبَلُ، وَأَمَّا الْمَالُ فَلَسْتُ مِنْهُ فِي شَيْء»
(As regards to your Islam, I accept it, but as for the property I do not take anything of it.)
`Urwah then started looking at the Companions of the Prophet . By Allah, whenever Allah's Messenger spat, the spittle would fall in the hand of one of them, who would rub it on his face and skin. If he ordered them, they would carry his orders immediately, if he performed ablution, they would struggle to take the remaining water, and when they spoke to him, they would lower their voices and would not look at his face constantly out of respect.
`Urwah returned to his people and said, `O people! By Allah, I have been to the kings and to Caesar [of the Romans], Khosrau [Kisra of Persia] and An-Najashi [the Negus of Ethiopia]. Yet, by Allah! I have never seen any of them respected by his courtiers, as much as, Muhammad is respected by his companions. By Allah, if he spat, the spittle would fall into the hand of one of them and he would rub it on his face and skin. If he ordered them, they would carry out his order immediately, if he performed ablution, they would struggle to take the remaining water, and when they spoke, they would lower their voices and would not look at his face constantly out of respect. No doubt, he has presented to you a good reasonable offer, so please accept it.'
A man from the tribe of Bani Kinanah said, `Allow me to go to him,' and they allowed him. When he approached the Prophet and his Companions, Allah's Messenger said,
«هذَا فُلَانٌ وَهُوَ مِنْ قَوْمٍ يُعَظِّمُونَ الْبُدْنَ فَابْعَثُوهَا لَه»
(He is so-and-so who belongs to the tribe that respects the sacrificial camels. So, bring the sacrificial camels before him.)
So, the sacrificial camels were brought before him and the people received him while they were reciting Talbiyah. When he saw that scene, he said, `Glorified is Allah! It is not fair to prevent these people from visiting the Ka`bah.' When he returned to his people, he said, `I saw the sacrificial camels garlanded and marked. I do not think it is advisable to prevent them from visiting the Ka`bah.'
Another person called Mikraz bin Hafs stood up and sought their permission to go to Muhammad , and they allowed him, too. When he approached the Muslims, the Prophet said,
«هَذَا مِكْرَزٌ وَهُوَ رَجُلٌ فَاجِر»
(Here is Mikraz and he is a vicious man.)Mikraz started talking to the Prophet and as he was talking, Suhayl bin `Amr came.'
