Salman reported,

When the Prophet ﷺ arrived in Medina, I prepared some food and brought it to him.He asked, "What is this, Salman?"I replied, "It is charity."He said to his companions, "Eat," but he himself did not eat.Then I went back and gathered more food and brought it to him.He asked, "What is this, Salman?"I replied, "It is a gift."So he extended his hand and ate, and he said to his companions, "Eat."I said, "Messenger of Allah, tell me about the Christians."He answered, "There is no good in them, nor in those who love them."I left feeling distressed, and then Allah عز وجل revealed, "You will surely find the most hostile of people toward the believers to be the Jews and those who associate others with Allah" until His words "their eyes overflow with tears" [Maidah 5:82–83].The Messenger of Allah ﷺ then sent for me and said to me, "Salman, your companions are the ones whom Allah has mentioned."

Sahih

عن سلمان قال

لما قدم النبي ﷺ المدينة صنعت طعاما، فجئت به النبي ﷺ، فقال: ما هذا يا سلمان؟ قلت: صدقة، فقال لأصحابه: كلوا، ولم يأكل، ثم إني رجعت حتى جمعت طعاما، فأتيته به، فقال: ما هذا يا سلمان؟ قلت: هدية، فضرب بيده فأكل، وقال لأصحابه: كلوا. قلت: يا رسول الله أخبرني عن النصارى؟ قال: لا خير فيهم ولا فيمن أحبهم، فقمت وأنا منقل، فأنزل الله عز وجل: {لتجدن أشد الناس عداوة للذين ءامنوا اليهود والذين أشركوا} حتى بلغ {تفيض من الدمع}، فأرسل إلي رسول الله ﷺ، فقال لي: يا سلمان إن أصحابك هؤلاء الذين ذكر الله.

His saying, "You will surely find the most intense of the people in enmity toward those who believe to be the Jews and those who associate others with Allah, and you will find the nearest of them in affection to those who believe to be those who say 'We are Christians.' That is because among them are priests and monks, and they are not arrogant. And when they hear what has been revealed to the Messenger, you see their eyes overflowing with tears because of what they have recognized of the truth. They say 'Our Lord, we have believed, so register us among'"
