Jesus VS Muhammad
Christianity and Islam are irreconcilably different. I will point out why that is because our Jewish masters force us to live together and sing kumbayah together in the name of tolerance.
So the best way to contrast the differences is to read about their character and teachings. This is about the exemplars of each religion. The persons that started the two biggest religions of the world. To be a perfect Christian means to model Jesus. And a perfect Muslim, to be like Muhammad. Everyone could agree on that. Muslims claim their prophet is the greatest man ever to live and Jesus is the epitome of perfection according to Christians.
I'll draw from historical accounts like the Gospels and Hadiths (Muhammad's life) to determine what both characters were like. Whether you believe the historical accounts are reliable or not, what matters is how they're depicted. Islamic tradition and Sahih Bukhari will be the main sources for determining who Muhammad was because they're the most trusted sources for mainstream Muslims (Sunni). Verses are taken from sunnah.com. You won't read non-Islamic sources about him.
Let's begin with Muhammad:
Muhammad's father died before he was born. Orphaned at the age of 6 and consequently adopted by his uncle. He married Khadijah at 25 when she was 40 and worked for her as a merchant. Muhammad took no other wives until she died. (Khadijah's age is not confirmed by the hadiths but comes from secondary sources.)
The Muslim prophet was a pagan for most of his life. He learned of Judaism and Christianity by interacting with Jews in the Arabian Peninsula. He greatly respected and affirmed the word of God given to the Jews. At 40, he started to receive revelations. Furthermore, he was disturbed by them but was reassured by his wife and cousin. He preached publicly about it much later. Opposition came after he denied the existence of other gods.
The situation in Mecca became unsafe because of his teachings. Muhammad's clan took refuge in Medina. Muhammad's relations deteriorated with the local Jewish tribes over time. 18 months after he emigrated, Muhammad raided Meccan caravans. During one of the raids, A Meccan force retaliated but was defeated by the Medinan Muslims. The Meccans launched two more campaigns to conquer Medina but failed.
After the wars, Muhammad personally oversaw the beheading of 700-900 adult men of the Qurayzah tribe. Including young teenage boys if they grew pubic hair. The remaining women and children were enslaved. Muhammad gained momentum after these battles. He continued to lay siege on the Jewish oasis Khaybar. The Jews were allowed to remain by sending tribute to Muhammad.
Meccan allies waged a war against the allies of Muhammad. In response, the prophet took up arms and laid siege to Mecca. The Meccans submitted to Muhammad. Afterward, he embarks on a campaign to the Syrian borders to put the locals under his submission in 630.
He died in 632 after a Jewish woman poisoned him four years prior.
Sahih Bukhari 5:59:713:
Narrated `Aisha: The Prophet (ﷺ) in his ailment in which he died, used to say, \"O `Aisha! I still feel the pain caused by the food I ate at Khaibar, and at this time, I feel as if my aorta is being cut from that poison.
Muhammad cursed the Jews and Christians in Allah's name as one of his last words before dying.
Sahih al-Bukhari 435, 436:
When the last moment of the life of Allah's Messenger (ﷺ) came he started putting his 'Khamisa' on his face and when he felt hot and short of breath he took it off his face and said, \"May Allah curse the Jews and Christians for they built the places of worship at the graves of their Prophets.\" The Prophet (ﷺ) was warning (Muslims) of what those had done.
Another significant fact is Muhammad betrothed his wife Aisha when she was 6 years old and penetrated her at 9.
Sahih al-Bukhari 5134:
Narrated `Aisha: that the Prophet (ﷺ) married her when she was six years old and he consummated his marriage when she was nine years old. Hisham said: I have been informed that `Aisha remained with the Prophet (ﷺ) for nine years (i.e. till his death).
But Muhammad wasn't a monogamist. He had 9 wives whom he often shared nights with.
Sahih al-Bukhari 5068:
Narrated Anas: The Prophet (ﷺ) used to go round (have sexual relations with) all his wives in one night, and he had nine wives.
To understand Muhammad's conquering tendencies we must look into his motivation. That is to spread Allah's truth.
Sahih al-Bukhari 392:
Narrated Anas bin Malik: Allah's Messenger (ﷺ) said, "I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah.' And if they say so, pray like our prayers, face our Qibla and slaughter as we slaughter, then their blood and property will be sacred to us and we will not interfere with them except legally and their reckoning will be with Allah.
You'll be free to choose to pay Jizyah (taxes) for being non-Muslim or face Jihad (holy war) when you refuse to pay according to Muhammad.
Muslims aren't commanded to kill you outright. Under sharia (Islamic law) you'll be considered a brother if you choose to convert. Whether out of your own free will or because of death threats.
Now let's look at Jesus' life:
Jesus was born in Bethlehem to Joseph and Mary. With Joseph as his legal father. Mary conceived as a virgin through the Holy Spirit. Because of Herod's threat to kill every two-year-old and under, the holy family fled to Egypt.
Jesus, Mary, and Joseph returned to Nazareth when Herod died. Growing up, Jesus spent much time in the Synagogue and was incredibly learned as a child. Not much is known about his life prior to his public ministry.
Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written.
He was a carpenter as Joseph was for most of his adult life. But his first significant public act was being baptized by John the Baptist. At Cana in Galilee, He performed his first sign of divinity. He turned water into wine. Followed by many other signs such as resurrecting the dead and healing the sick.
Now he gained many followers by teaching. A pivotal moment was his Sermon On The Mount. Jesus showed how radically different He is from other gods and their teachings.
Love your enemies
You shall not commit adultery
Blessed are the peacemakers
What's so pivotal about Jesus' teachings is the blow against the status quo. The Pharisees. They hated Him. Jesus taught that salvation isn't achieved through legalism but through a true change of heart. A change of faith. He wants your heart, and you can only give it to Him freely. That makes Jesus' teaching unique.
Beware of practicing your righteousness before men to be noticed by them; otherwise you have no reward with your Father who is in heaven.
A crucial moment in Christ's teaching. He sets himself apart from teachers like the prophets that came before Him by being the authority as written in the verse below.
When Jesus had finished these words, the crowds were amazed at His teaching; for He was teaching them as one having authority, and not as their scribes.
Jesus was arrested by the Pharisees. His claims of being God got Him killed by the Jewish authorities. He willingly got along because He was there to fulfill the prophecies of the Old Testament.
After being brutalized, bleeding, and hanging on the Cross His heart was set on forgiveness.
Jesus said, “Father, forgive them, for they do not know what they are doing.” And they divided up his clothes by casting lots.
After his crucifixion and resurrection, he stayed for 40 days with His mother and disciples. He ascended into heaven as witnessed by his disciples.
And he led them out as far as Bethany, and lifting up his hands he blessed them. While he blessed them, he parted from them and was carried up into heaven. And they worshiped him and returned to Jerusalem with great joy, and were continually in the temple blessing God.
You're going to have to come up with your own conclusion about Jesus' and Muhammad's character. However, one thing is certain, with such striking differences, it's impossible to find peace among Christians and Muslims if they truly follow their role model. Unity between them is a lie.
