"So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets" (Matthew 7:12).
"But I say to you who hear, Love your enemies, do good to those who hate you, bless those who curse you, pray for those who abuse you [. . .] as you wish that others would do to you, do so to them.
"If you love those who love you, what benefit is that to you? For even sinners love those who love them. And if you do good to those who do good to you, what benefit is that to you? For even sinners do the same. And if you lend to those from whom you expect to receive, what credit is that to you? Even sinners lend to sinners, to get back the same amount. But love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be sons of the Most High, for he is kind to the ungrateful and the evil. Be merciful, even as your Father is merciful" (Luke 6).On the other hand:
"The punishment of those who wage war against Allah and His Messenger, and strive with might and main for mischief through the land is: execution, or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter . . . " (Qur'an 5:33).
[Ibn Kathir says of this verse: "'Wage war' mentioned here means, oppose and contradict, and it includes disbelief, blocking roads and spreading fear in the fairways. Mischief in the land refers to various types of evil." So, Muhammad requires execution, crucifixion, or cutting off hands and feet from opposite sides for "disbelief."]
"Allah's Apostle said: 'I have been ordered (by Allah) to fight against the people until they testify that none has the right to be worshipped but Allah and that Muhammad is Allah's Apostle . . . '" (Bukhari Volume 1, Book 2, Number 24).
"It is not for any prophet to have captives until he hath made slaughter in the land. Ye desire the lure of this world and Allah desireth (for you) the Hereafter, and Allah is Mighty, Wise" (Qur'an 8:67).
"Allah’s Apostle said, 'I have been made victorious with terror'" (Bukhari Volume 4, Book 52, Number 220).
"My mother came to me while I was being swung on a swing between two branches and got me down. My nurse took over and wiped my face with some water and started leading me. When I was at the door she stopped so I could catch my breath. I was brought in while Muhammad was sitting on a bed in our house. My mother made me sit on his lap. The other men and women got up and left. The Prophet consummated his marriage with me in my house when I was nine years old” (Tabari 9:131).
