How Surah Al-Kafirun' was Revealed?

He said: Abu Muhammad b. Abdullah b. Abu Sheik reported to me with permission to report from Abu Abdillah Muhammad b. Ahmad al-Hakimi, who reported from Abdul Rahman b. Abdillah Abu Saeed al-Basri, who reported from Wahab b. Jareer, from his father, who reported from Muhammad b. Ishaq b. Yasar al-Madani, who reported from Saeed b. Meena, from more than one companions, that: A group of Quraish comprising of Utbah b. Rabeeah, Umayyah b. Khalaf, Waleed b. al-Mughaira and al-Aas b. Saeed once confronted the messenger of Allah, peace be upon him and his progeny, saying:
"O Muhammad, let us compromise, so that we worship what you worship, and you worship what we worship, and thus both of us come to an equitable word in this matter. If the truth is with us, you will have shared it, and if the truth is with you, we will have our share from it." So Allah revealed (unto the Prophet): 'Say, O unbelievers! I do not worship what you worship; nor do you worship what I worship; nor do I worship what you have worshipped, nor do you worship what I worship. You have your religion and I have mine.' (al-Kafirun:109)"
Then once Ubay b. Khalaf came with withered bones and crushed them in his hands. Then blowing it up, he said: "O Muhammad, do you claim that your Lord will give life to what you now see?" Then Allah revealed (unto the Prophet): 'And he produced an equal for Us, forgetting Our creating him; he said: Who brings the bones back to life, once they are withered? Say: He who originated them the first time will bring them back to life, and He has knowledge of every creation.' (Yasin:36); till the end of the Surah."
