Once Mu’aviah, the first Umayyad Caliph, ordered Sa’d ibn Abi-Waqass -a famous companion of the Prophet (PBUH & HP)- to insult Imam Ali (AS). Mu’aviah was the enemy of Imam Ali (AS) and would order people to say bad things about him in public. But Sa’d refused to do that.Mu’aviah said: why don’t you insult “Aba-Turab” (Imam Ali)? Sa’d replied: I won’t insult Aba-Turab because I remember him in three events that if those had happened to me it would be better for me than having so many red camels (symbol of richness) Sa’d narrated three stories about Imam Ali (AS) but, here, we mention the third one: 

… Once this verse was revealed to the Prophet (PBUH&HP):

فَمَنْ حَاجَّكَ فِيهِ مِن بَعْدِ مَا جَاءَكَ مِنَ الْعِلْمِ فَقُلْ تَعَالَوْا نَدْعُ أَبْنَاءَنَا وَأَبْنَاءَكُمْ وَنِسَاءَنَا وَنِسَاءَكُمْ وَأَنفُسَنَا وَأَنفُسَكُمْ ثُمَّ نَبْتَهِلْ فَنَجْعَل لَّعْنَتَ اللَّهِ عَلَى الْكَاذِبِينَ ‎﴿٦١﴾‏

Should anyone argue with you concerning him (Jesus), after the knowledge that has come to you, say, ‘Come! Let us call our sons and your sons, our women and your women, our souls and your souls, then let us pray earnestly, and call down Allah’s curse upon the liars.’ (61) (The Holy Quran, 3:61)

The Prophet (PBUH & HP) called Ali, Fatimah, Hassan and Hussain and then said: “O God! These are my family” (1)

The Christians of Najran 

When Prophet Muhammad (PBUH & HP) sent messages to the kings around the world and invited them to Islam, he also wrote a letter to the bishop of Najran’s church (a city in Arabia). 

They sent a group of priests and Christian scholars to talk with the Prophet (PBUH & HP) and discuss with him on the Message of Islam. They discussed on the question: Is Jesus the son of God or not? 

Each side insisted on their beliefs and the Christians wouldn’t accept that their belief is wrong. Then this verse was revealed to the Prophet (PBUH & HP):

Indeed the case of Jesus with Allah is like the case of Adam: He created him (Adam) from dust, then said to him, ‘Be,’ and he was. (59) This is the truth from your Lord, so do not be among the skeptics. (60) Should anyone argue with you concerning him (Jesus), after the knowledge that has come to you, say, ‘Come! Let us call our sons and your sons, our women and your women, our souls and your souls, then let us pray earnestly, and call down Allah’s curse upon the liars.’ (61) (The Holy Quran, 3:59-61)

So Allah said to the Prophet (PBUH & HP) that the only way to clarify which side is telling the truth is Mubahala.

What does Mubahala mean?

When two groups of people have an argument with each other, after so many discussions with no results, they come to a place and call down Allah’s curse upon the liars. They pray that Allah punishes the ones who tell lies right in the time. This is called Mubahala. 

The Prophet’s family 

So, both sides agreed and promised to be present on a specific day (Du al-Hijjah the 24th) in the desert for Mubahala. In the morning of Mubahala day, the Messenger of Allah came to Imam Ali’s house and took Imam Hassan and Imam Hussain’s hands. The Prophet, Imam Ali, Lady Fatimah, Imam Hassan and Imam Hussain went to the desert. 

When the Christians saw them, asked: who are those people with Muhammad?

They were answered: that man is his cousin and son in law. He loves Ali the most. Those children are his grandsons and that woman is his lovely daughter.

The Christians said: Muhammad is sitting there like the real Prophets. If he wasn’t right, he wouldn’t bring the closest ones with him for Mubahala. He must be so sure about his message. If we participate in this Mubahala, there will be no Christian left in Najran till next year. 

So they refused to participate in the Mubahala and went back to Najran. 

What do Sunni scholars say about this event?

•    Hakim an-Neisaboori, one of the most prominent Sunni scholars, says:

“There are so many historical records concerning this event that the Messenger (PBUH & HP) brought Ali, Fatimah, Hassan and Hussain in the Mubahala day and then said: “these are our sons and our souls and our women so you (Christians) bring your sons and souls and women for Mubahala so that we call down Allah’s curse on the liars” (2)

•    Ibn Kathir, another great Sunni scholar also admits that this verse is about Imam Ali, Lady Fatimah, Imam Hassan and Imam Hussain. He says that Jabir ibn Abdullah al-Ansari (one of the most important companions of the Prophet) said:

“By ‘our souls’ Allah means the Prophet (PBUH & HP) and Imam Ali (AS)” (3)

Here soul, in Arabic culture, means that Imam Ali (AS) is so close to the Prophet (PBUH & HP) that there is no difference between him and the Prophet; it’s like they are one soul in two bodies. Obviously, the only difference is that Imam Ali is not a prophet but on the other levels Imam Ali and the Prophet are the same. 

Imam Reza (AS) and Mubahala 

Sheik Mufid, one of the greatest Shiite scholars, narrates a dialogue between Imam Reza (AS) and Ma’moon (an Abbasid Caliph):

Once, Ma’moon asked Imam Reza (AS) about the best privilege of Imam Ali (AS) that the Quran has mentioned. 

Imam Reza (AS) said: it is the event of Mubahala. In that day when the verse was revealed to the Prophet (PBUH&HP), he called Imam Hassan and Imam Hussain, who were his sons, Lady Fatimah, who was the woman mentioned in the Quran, and finally Imam Ali which was the soul mentioned in the Book. 

Imam Reza (AS) also said: clearly the Prophet (PBUH & HP) is the most supreme person in the world. So it is obvious that his soul which is Imam Ali is also the most supreme creature. 

Ma’moon said: why don’t you think that here soul means the Prophet himself and no one else?

Imam Reza (AS) said: because it doesn’t make sense to call yourself and bring yourself for Mubahala. When you call somebody or order somebody to come with you, it is obvious that the person is not yourself. And we all know that the Prophet brought no one except Imam Ali; so undoubtedly, Imam Ali is his soul. 

Ma’moon said: with this answer, there is no question left! (4)

On Dhu al-Hijjah the 18th AH (March 632 CE), Prophet Muhammad (PBUH & HP), while returning from his last pilgrimage of Hajj named “the Farewell Hajj”, stopped at Ghadir Khumm (a pond) to make an announcement to the pilgrims who had accompanied him in the pilgrimage.

Ghadir Khumm was a place where people (who were about 10 thousand in number) from different lands like Iraq, Syria, and Egypt would part ways. But before they do, Gabriel revealed to the Prophet (PBUH & HP) one of the last verses of Quran. The verse is now called the verse of al-Tabligh (propagation):

يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنزِلَ إِلَيْكَ مِن رَّبِّكَ وَإِن لَّمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ وَاللَّهُ يَعْصِمُكَ مِنَ النَّاسِ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الْكَافِرِينَ

O Messenger! Communicate that which has been sent down to you from your Lord, and if you do not, you will not have communicated His message (the whole message of Islam), and Allah shall protect you from the people. Indeed Allah does not guide the faithless lot. (The Holy Quran 5:67)

After the verse was revealed to the Prophet (PBUH & HP), he ordered the caravan to stop and ordered those who have passed Ghadir Khumm return and wait until those who had not yet arrived there join them. (1)

After performing the noon prayer, the Prophet (PBUH & HP) made a speech that now is one of the most famous speeches of the Prophet known as Ghadir sermon. Zeid ibn Argham, one of the famous companions of the Messenger (PBUH & HP) said:

“Once, the Messenger of Allah (PBUH & HP) made a speech for us near a pond named Ghadir which is between Mecca and Medina. Firstly, he praised Allah and talked about God and then said: ‘O people! I’m only a human and it is possible that the Apostle of my God (The angel of death) comes to me and I shall accept his invitation (my life ends) and I am leaving you al-Thaqalayn (two great things). The first one is the book of Allah (Quran) in which is guidance and light so follow it and hold fast to it.’ he advised us about the Book and encouraged us to follow it. Then the Prophet (PBUH) said: ‘and (the second one is) my close family.  By Allah, I advise you (to follow) my family, By Allah, I advise you (to follow) my family, By Allah, I advise you (to follow) my family’” (2) 

The Hadith above is known as “al-Thaqalayn”. It is one of the most famous Hadiths of the Prophet (PBUH & HP) which indicates that the most important things which the Prophet has left for all Muslims are Quran and the family of the Prophet. 

Bara’ ibn Azib, another famous companion of the Messenger, narrates the continuation of the Hadith: 

“Then the Prophet raised Ali’s hand (so that all people can see it) and said: ‘don’t you know that I am more deserved to the leadership of the believers than themselves?’. People said: ‘yes, we know’. The Prophet said again: ‘don’t you know that I am more deserved to be the leader of every believer than themselves?’. People said: ‘yes, we know’. Then the Prophet said: ‘anyone whose Mawla is me, then Ali is his Mawla. O God! Be friends with his friends and be enemy of his enemies’. Then, Umar ibn Khattab (the second Caliph) met Ali and told him:

‘Congratulations to you, Congratulations to you, you just got the Mawla of every believer, men or women’” 

Arna’oot, one of the most important religious Sunni researchers admits that this historical record is right and trustable. (3)

What does the word “Mawla” mean?

The word “Mawla” in Arabic language has lots of meanings. Shias and Sunnis disagree on the meaning of the word used in this hadith. 

Sunni viewpoint 

Sunni scholars mostly refuse to believe that the word “Mawla”, used in the Hadith, means “Leader” or “Prior in making decisions for somebody”. They rather suggest it means “friend or helper”. They argue that this word is never used in this meaning (Leader). 

Shiite viewpoint 

Shiites, in reply to Sunni scholars, say that this world have actually been used in this meaning (“the prior”) and some Sunni scholars have admitted that. (4) also, some experts in Arab literature admitted so too like Ghiyath Barghuth, Ajjaj (5), Yahya ibn Ziad al-Farra, Akhfash and so forth. (6)

To prove that the word Mawla in this Hadith means “Leader” and not “friend”, there are many evidences but we mention just one in this text. 

The congratulation of Umar ibn Khattab:

The congratulation of Umar ibn Khattab can be a good evidence to prove that “Mawla” here doesn’t mean “friend”. Because, as we said before, Umar says: “Congratulations to you, you just got the Mawla of every believer, men or women” while Imam Ali was the friend of every believer before the Ghadir event, and it doesn’t make sense that he just got the friend of believers in there. 

Ghazali, one of the most important reflective Sunni scholars in this regard, says:

“(After the sermon) Umar said: ‘Congratulations O Aba al-Hassan (Imam Ali (AS) ), you just got my friend and every believer’s friend’. So this shows submission and satisfaction (that Imam Ali is the successor of the Prophet) but after this event, due to his desire and love for power, he made himself Caliph and leader” (7) 

Revelation of the Ikmal verse

People had not scattered yet, when Gabriel one more time came to the Prophet and revealed another verse to him:

الْيَوْمَ يَئِسَ الَّذِينَ كَفَرُوا مِن دِينِكُمْ فَلَا تَخْشَوْهُمْ وَاخْشَوْنِ الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا

Today the faithless have despaired of your religion. So do not fear them, but fear Me. Today I have perfected your religion for you, and I have completed My blessing upon you, and I have approved Islam as your religion.

The narrators of the Hadith 

The Hadith is that which is frequently narrated by different people and historians that no one can deny its authenticity. 

The family of the Prophet i.e. Imam Ali himself, Lady Fatima, Imam Hassan and Imam Hussain are among the narrators of this Hadith. Also many of the companions of the Messenger narrated this Hadith. Kattani, one of the Sunni scholars, says that about 30 companions of the Prophet narrated this story including: Umar ibn Khattab, Zeid ibn Argham, Abi Hurairah, Sa’d ibn Waghas and etc. (8) 

Due to this fact that this Hadith is so frequently narrated, it is called “Mutavatir”, meaning that this Hadith is undeniable. 

Eid al-Ghadir

Shi'as have always regarded the Day of Ghadir as one of the greatest Eids and this day is known to them as Eid al-Ghadir. Imam Sadiq (AS) says that the Eid al-Ghadir is the greatest Eid of Allah. Its name in skies is “the day of Promise” and in the earth “the day of Covenant”. (9)
Shiites believe that this day was the day that Imam Ali (AS), our first Imam, was officially announced to be the successor of the Prophet (PBUH & HP). So this day is a great holiday for them and fasting in it is so recommended. In this day, Shiites go to the house of Seyyed people -the descendants of Imam Ali and Lady Fatimah- and congratulate them. In return, Seyyed people give them gifts. It is highly recommended to conduct parties in this day and give food to the needy ones.
