Also known as the greatest commandment, in NIV Matthew 22:34-40:
The Greatest Commandment
34 Hearing that Jesus had silenced the Sadducees, the Pharisees got together. 35 One of them, an expert in the law, tested him with this question: 36 “Teacher, which is the greatest commandment in the Law?”
37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ 38 This is the first and greatest commandment.
39 And the second is like it: ‘Love your neighbor as yourself.’
40 All the Law and the Prophets hang on these two commandments.”
NIV Matthew 22:34-40

Note the words of Jesus: “All the Law and the Prophets hang on these two commandments.”. Compare that to the words of Muhammad, who’s unable to even copy the words of Jesus, let alone act upon them or promote them in his life, his recitation, his Koran.
