In this place, the following verse of the Qur'an was revealed:
"O Apostle! Deliver what has been sent down to you from your Lord; and if you don't do it, you have not delivered His message (at all); and Allah will protect you from the people ..." (Qur'an 5:67)
The last sentence in the above verse indicates that the Prophet [s] was mindful of the reaction of his people in delivering that message but Allah informs him not to worry, for He will protect His Messenger from people.
