When Prophet Muhammad (PBUH&HP) was writing letters to the Heads of neighboring states, he referred to Jesus Christ (PBUH) as the messenger of Allah and then invited them to Islam. In his letter to Nagaci, the king of Ethiopia, he wrote: 

“… He, the King, the Holy peace insured dominant, and I bear witness that Jesus son of Mary, the Spirit of Allah and his speech was delivered to the Virgin Mary the good bunker. Allah created Jesus from his soul, just as he created Adam with his hand, and I invite you and your soldiers to Allah Almighty, has reached and advised receive my advice, and peace be upon those who follow guidance”.

Insisting on the fact that he knew Jesus (PBUH) and that he was the son of Mary, he wanted them to know that Islam is no different from true Christianity. The Quran, on the other hand, insists on this and reveals the fact that his name was stated before in the holy books:

 "Those who follow the Messenger, the unlettered prophet, whom they find written in what they have of the Torah and the Gospel, who enjoins upon them what is right and forbids them what is wrong and makes lawful for them the good things and prohibits for them the evil and relieves them of their burden and the shackles which were upon them. So they who have believed in him, honored him, supported him and followed the light which was sent down with him - it is those who will be the successful." (7:157)

But is that true? 

Here we are going to discuss some of those verses and words.

 1. Prophet Muhammad (PBUH&HP) in Deuteronomy 

“I will raise up a prophet from among their countrymen like you, and I will put My words in his mouth, and he shall speak to them all that I command him. It shall come about that whoever will not listen to My words which he shall speak in My name, I Myself will require it of him. But the prophet who speaks a word presumptuously in My name which I have not commanded him to speak, or which he speaks in the name of other gods, that prophet shall die.”(18:18)

Al-Samawal Al-Maghribi was a Jewish mathematician who converted to Islam and had interpretations of the verses of the Old and New Testament. He interprets this verse as referring to Prophet Muhammad (PBUH&HP). The description given in this verse about the future prophet is referring to Prophet Muhammad (PBUH&HP) since it’s similar to the description given before about the children of Esau (Jesus). There is another verse that is referring to Prophet Muhammad (PBUH&HP) in his point of view: 

"The Lord came from Sinai, and dawned on them from Seir; He shone forth from Mount Paran, And He came from the midst of ten thousand holy ones; At His right hand there was flashing lightning for them.” (33:2)

Al-Maghribi states that in this verse, Mount Sinai refers to Moses, Mount Seir refers to Jesus, and Mount Paren refers to Prophet Muhammad (PBUH&HP). [1] 

2. Prophet Muhammad (PBUH&HP) in Isaiah

This chapter is shared between the Hebrew Bible and the Old Testament of the Christian Bible. In verses 1 to 4 of this chapter, we read: 

“Behold, My Servant, whom I uphold; My chosen one in whom My soul delights. I have put My Spirit upon Him; He will bring forth justice to the nations. "He will not cry out or raise His voice, Nor make His voice heard in the street. "A bruised reed He will not break and a dimly burning wick He will not extinguish; He will faithfully bring forth justice. "He will not be disheartened or crushed Until He has established justice in the earth; And the coastlands will wait expectantly for His law.” (42:1-5)

According to the verses above, a prophet was coming from the children of Qedar, the second son of Ishmael [2], and also the nomadic Arab tribe, which was known as the most significant organized Arab tribe [3]. He is also sent to the same tribe to guide them on the right path. The other point about the prophethood of Muhammad (PBUH&HP) mentioned in this verse is that his religion was universal, willing to stand against gods and goddesses. Everyone waited for his coming, and different tribes would follow him. 

3. Prophet Muhammad (PBUH&HP) in John 

“I will ask the Father, and He will give you another Helper, that He may be with you forever; that is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him, but you know Him because He abides with you and will be in you. “ (14:16-17)

Muslims’ interpretation of this verse states that the two words meaning comforter and famous, were used interchangeably and Jesus in prophesying the coming of Prophet Muhammad (PBUH&HP). [4] They also relate these verses to a verse of the Quran about Jesus Christ, telling his people about the coming of the next prophet:  

“And [mention] when Jesus, the son of Mary, said, "O children of Israel, indeed I am the messenger of Allah to you confirming what came before me of the Torah and bringing good tidings of a messenger to come after me, whose name is Ahmad." But when he came to them with clear evidence, they said, "This is obvious magic.” (61:6)

According to this verse, the name Ahmad is given for Prophet Muhammad (PBUH&HP), and it means the praised one. According to the translations of the holy bible, the word periklutos means the celebrated or praised one means Ahmad. The word is repeated in John 14, John 15 and 16.

According to the verses above, the coming of Muhammad (PBUH&HP) was prophesied by the former prophets. And many Jews and Christians were aware of the coming of a new prophet. However, many of them rejected his invitation. Why?

In the previous part of this topic, we emphasized that advertising peace and educating peaceful followers are of the main purposes of Islam. Here we review some more Islamic pieces of advice and lessons on having a balanced life and being in peace with other people of either the same religion or other.  

Being Good-Tempered

Being equable and good-tempered, and avoiding irascibility and harsh words are continuously advised to in the Islamic teachings such that Prophet Muhammad (PBUH) is invited in the Quran to “argue with them (unbelievers) in a way that is best” (16:125). Prophet Muhammad (PBUH) and Imams (AS), as role models for Muslims, have demonstrated these acts in a way that the Quran says about the Prophet (PBUH): “And indeed, you are of a great moral character” (68:4). That is why the Quran says about Prophet Muhammad (PBUH): “So by mercy from Allah, you were lenient with them. And if you had been rude [in speech] and harsh in heart, they would have disbanded from about you” (3:159).

Imam Sadiq (AS) has described being good-tempered as: “using friendly words, nice behavior and receiving your brother happily” [1]. Imam Ali (AS) said that the best and most important deed of a “believer” is behaving nicely with people [2]. Even in the case of facing ignorant people, it is encouraged to treat kindly: “And the servants of the Most Merciful are those who walk upon the earth easily, and when the ignorant address them [harshly], they say [words of] peace” (25:63). 

These examples and many other Islamic pieces of advice demonstrate how much Islam cares about one’s behavior towards others. 

Moderation in All Affairs 

This is true that moderation can develop peace. Islam recognizes moderation as the most efficient and pleasant approach in life and interaction with others. Prophet Muhammad (PBUH) said that: “the best of every affair is the middle of it” [3]. The Quran describes Muslims as a moderate community and says that: “we have made you a just community that you will be witnesses over the people and the Messenger will be a witness over you” (2:143). This means that the nation and people who are educated based on the Islamic teachings and the Quranic guidelines will avoid extremes; neither they are radical, nor conservative [4]. 

However, whenever the truth (Haq) and falsehood (Batil) are clear and apparent, there is no place for moderation. An example is the holy struggle (Jihad); i.e., when land is attacked by others, there should be no moderation and defense becomes obligatory. 

The Rights of Non-Muslims in peace

Islam has considered the rights for every being, from parts of the body to neighbors, parents, etc. Then, it is not surprising if Islam also considers some rights for non-Muslims over Muslims. Of the rights of non-Muslims are to believe in the promises they have given the Islamic state; not to bother them about what they want or on what they are obliged to; to judge among them just as God has ordered; not to oppress them since Prophet Muhammad (PBUH&HP) said that he would be against anyone who oppresses a non-Muslim1 [5]. Imam Ali (AS) was sensitive to any harm or injustice to whether Muslims or non-Muslims. He (AS) said that: “if someone is not of your religion, he is still a human being like you.”, he (AS) was therefore against any harm or damage to non-Muslims [6].

Dealing with Others in the Early Ages of Islam

After the rise of Islam, Prophet Muhammad (PBUH&HP) adopted the approach of moderation and fairness with the followers of the previous Abrahamic religions. 

Prophet Muhammad (PBUH&HP) defended boldly Muslims and himself whenever needed. He (PBUH&HP) opposed any violence to Muslims, but he (PBUH&HP) still cared about the prisoners of the wars. He (PBUH&HP) had ordered to treat them with moderation, mercy, and humanity, to do good to them and to forgive them. Prisoners were usually kept in the mosques or proper and clean homes. The troops of Islam, following the manner of Prophet (PBUH&HP), preferred prisoners to themselves such that they provided prisoners with better foods and clothes. If a prisoner did not want to reveal the secrets of the enemies, he would not be beaten but whoever did so would be released [7].    

Considering the points mentioned above about how Islam educates peaceful followers and how it considers rights for non-Muslims, the role of Islam in promoting peace can be fully grasped. However, this should not be confused that a Muslim must endure every situation or the violation of his\her rights or the rights of the Muslims in general. The key point is that a Muslim chooses the moderation and peace as the first solution to his social affairs as long as it does not require the violation of the rights of one or several people. 

1 Here, the term “non-Muslim” refers only to a non-Muslim who is the citizen of an Islamic state or a non-Muslim who lives in a non-Muslim country which is in agreement with Muslims.
