Jesus believed in one God
Jesus replied, "The most important commandment is this: 'Listen, O Israel! The LORD our God is the one and only LORD. (Mark 12:29)
Islam: And your Ilah (god) is one Ilah (god - Allah), La ilaha illa Huwa (there is none who has the right to be worshipped but He), the Most Gracious, the Most Merciful. (Holy Quran 2:163)
Jesus was circumcised
On the eighth day, when it was time to circumcise the child, he was named Jesus, the name the angel had given him before he was conceived. (Luke 2:21)
islam: Narrated Abu Huraira: Allah's Apostle said, "Five practices are characteristics of the Fitra: circumcision, shaving the pubic region, clipping the nails and cutting the moustaches short." (Bukhari Book 72 Hadith 777)
World Health Organisation Statistic Map showing the areas of circumcision,as can be seen Muslim populated countries are circumcised the most.
Jesus fasted for more than a month
For forty days and forty nights he fasted and became very hungry. (Matthew 4:2).
Islam: Muslims are required every year to fast during the month of Ramadan - Ramadhan is the (month) in which was sent down the Qur'an, as a guide to mankind, also clear (Signs) for guidance and judgment (Between right and wrong). So every one of you who is present (at his home) during that month should spend it in fasting, but if any one is ill, or on a journey, the prescribed period (Should be made up) by days later. Allah intends every facility for you; He does not want to put to difficulties. (He wants you) to complete the prescribed period, and to glorify Him in that He has guided you; and perchance ye shall be grateful. (Holy Quran 2:185).
Jesus used the peace be with you greeting
Islam: Abu Huraira reported: The Messenger of Allah (may peace and blessing be upon him) observed: You shall not enter Paradise so long as you do not affirm belief (in all those things which are the articles of faith) and you will not believe as long as you do not love one another. Should I not direct you to a thing which, if you do, will foster love amongst you: (i. e.) give currency to (the practice of paying salutation to one another by saying) as-salamu alaikum. (Sahih Muslim Book1, Hadith 96)
Jesus promoted modesty
But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. (Matthew 5:28)
Islam: tell the believing men to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts). That is purer for them. Verily, Allah is All-Aware of what they do. (Holy Quran 24:30)
Jesus prayed like a Muslim
He went on a little farther and bowed with his face to the ground, praying, "My Father! If it is possible, let this cup of suffering be taken away from me. Yet I want your will to be done, not mine." (Matthew 26:39)
Many other examples which other members may share!
Jesus never called himself a Christian yet those people who call themselves Christians say they are followers of Jesus. Like many things in Christianity, the world Christian was invented after Jesus left the people. Jesus was a Muslim. A Muslim is one who submits themselves to God, Islam is the religion of submission to God. Jesus worshipped the same God Muslims worship. Islam is not a religion that was introduced by the prophet Muhammad pbuh but rather he was the final prophet to come and complete the religion. The quran emphasises the belief in all the prophets as they were all one of the same faith, in submission to their Creator, Allah.
Say ye: "We believe in Allah, and the revelation given to us, and to Abraham, Isma'il, Isaac, Jacob, and the Tribes, and that given to Moses and Jesus, and that given to (all) prophets from their Lord: We make no difference between one and another of them: And we bow to Allah (in Islam)." (The Holy Quran 2:136)
