When it comes to how Islam was spread universally, we hear from many that Islam was spread by sword and bloodshed. However, studying the conduct and manner of all the prophets,  and especially Prophet Muhammad (PBUH&HP), in inviting people to Allah unveils the truth about this issue.  

When one decides to start a revolutionary cultural movement, he/she needs to plan for different aspects of this movement. The most important thing is the message he/she wants to convey to the audience. After that, he/she comes to how to spread this message in a way that can be vastly heard, and then it’s time to discover how the message should be said and conveyed to attract the audience. This is the most primary rule in media studies, and prophets in their era were well-aware of these rules and if they needed help regarding techniques and concepts, they received guidelines from Allah to help them spread their message in the most influential way. 

The messages that prophets were going to convey to people were revealed to them by God Allah. The question ‘“how to spread this message” is discussed as a method of invitation. And the question ‘how to make the words influential’ is discussed under the title of manners of invitation in this article. 

The mission of Prophet Muhammad (PBUH&HP)

Allah (SWT) highlights the mission of His Prophet (PBUH&HP) as follows: 

“O Prophet! Indeed We have sent you as a witness, as a bearer of good news and as a warner. And as a summoner to Allah by His permission, and as a radiant lamp.” (33: 45-46)

In this verse, the Prophet (PBUH&HP) is introduced as a “witness” [1]; a person who is present in his society and observes the problems and challenges of people on one hand, and as a person who has the best capability to testify the truth about Allah, His creation, and the hereafter on the other.   

He has the responsibility to invite people to Allah, inform and remind them of the mercy and blessings of their lord and warn them of what is harmful to them. He, as a “radiant lamp” lightens the path of his people toward prosperity. [1].

The methods

But, has God Allah provided His prophet Prophet ((PBUH&HP) with any methods to help him guide people?

In some verses of the Quran Allah (SWT) provides the Prophet (PBUH&HP) with the following methods: 

“Invite to the way of your Lord with wisdom and good advice and dispute with them in a manner that is best...” (16:125)

  Inviting with wisdom

Using this verse, the first step in inviting people to God Allah is to use correct wisdom and reasoning, and since the mission of the Prophet of Islam (PBUH&HP) is to awaken thoughts and ideas and to flourish rational treasures, the best way to achieve this goal is to use logic and reasoning. [2] This method is mostly used for those intellectual people of the society. 

1- Inviting with good advice

The verse introduces “good advice” as a method for communicating with the audience who have softer hearts. “Good advice” is the method in which good deeds are reminded and expressed in such a way that the listener's heart is softened by hearing that expression and, as a result, surrenders. Therefore, for some audience gentle speech is more effective than logical arguments. [4]

2- Inviting with dispute

However, for a group of audience who are stubborn and have prejudice on their ideas, the Quran suggests the method of dispute and argument in a way that is best. 

The definition of “best despite” can be best understood when recognizing what is a wrong dispute. A wrong dispute or argument as described by Imam Sadiq (AS) is “a disgraceful, immodest argument to deny a right, or to accept a falsehood, as a result of your own intellectual weakness, or to do so as a result of the abuse of a rival's intellectual weakness.” [5] 

Therefore, the best dispute is the one in which both parties listen to each other with the intention of learning from and informing each other, and accepting the truth and justice even if it is against our mindset.

3- Based on awareness

In another verse of the Quran Allah (SWT) Commands His prophet Prophet (PBUH&HP) to: 

“Say, ‘This is my way. I summon to Allah with insight—I and he who follows me. Immaculate is Allah, and I am not one of the polytheists.’” (12:108)
In fact, the Prophet of Islam (PBUH&HP), by the command of GodAllah, determines his religion and method to invite all people to this path out of awareness and insight. The followers of the Prophet (PBUH&HP) must also invite the people to the divine religion with awareness and insight.

The manners of prophet Muhammad (PBUH&HP)

Apart from all the methods that Prophet Muhammad (PBUH&HP) knew them well, it was his manner that attracted people to him and his message. 

Mercy to mankind

As Allah mentions in the Quran, Prophet Muhammad (PBUH&HP) was sent to humanity as a mercy and blessing: 

“We did not send you but as a mercy to all the nations.” (21:107) 

Although the great manner and behavior of Prophet Muhammad (PBUH&HP) has been admired in the Quran [6], the difficulty of his mission in interacting with people has been so great that Allah puts mercy and gentleness in his heart: 

“It is by Allah’s mercy that you are gentle to them; and had you been harsh and hardhearted, they would have surely scattered from around you. So excuse them and plead for forgiveness for them, and consult them in the affairs, and once you are resolved, put your trust in Allah. Indeed Allah loves those who trust in Him.” (3:159)

This verse shows that his kind attitude and his sympathy with people has been one of the main tools he used in inviting people to God.Allah.

From among people

Other absorbing characteristics of Prophet Muhammad (PBUH&HP) are mentioned in another verse of the Quran: 

“There has certainly come to you an apostle from among yourselves. Grievous to him is your distress; he has a deep concern for you, and is   most kind and merciful to the faithful.” (9:128)

The verse emphasizes on the fact that the prophet Prophet (PBUH&HP) was one of the people, not considering himself higher than them. He was a man who was so compassionate to the people, and his mind was all concerned about their problems and their life in this world and in the hereafter. 
Although this verse ends with the phrase that he was kind to faithful people, another verse of the Quran shows that he tried so hard to guide and help the unfaithful. So much that Allah (SWT) told him 

“you are liable to imperil your life [out of distress] that they will not have faith.” (26:3)

In sum, the Prophet of Islam (PBUH&HP) used all correct logical, psychological, scientific, and behavioral methods to invite people to truth and the soul of his merciful invitation still flows all over the world through the hearts of the truth-seekers.

The Holy Quran is replete with examples of men who stood for the truth and those who opposed it. The former sacrificed everything they had to defend the truth and the latter was ready to destroy everything around them to satiate their greed and selfishness.

The Book of Allah invites us to reflect upon personalities, nations, and events of the past. Whether it is pure men like Prophet Ibrahim (AS), Prophet Musa (AS) and Prophet Isa (AS) or evil men who opposed them and their mission like Nimrood, Firon (Pharoah), or Bani Israil, all of them have a lesson for us. These are not just stories to read and move on, they contain messages for our lives. And rightly so, we read in the Holy Quran:
"There is certainly a moral in their accounts for those who possess intellect. This [Quran] is not a fabricated discourse; rather, it is a confirmation of what was [revealed] before it, and an elaboration of all things, and a guidance and mercy for a people who have faith. (12:111)

Similarly, Imam Ali (AS) says: Learn lessons from past events for future events, because they are similar to one another. (Nahjul Balagha Letter 69)
One such incident of the past that changed the history of Islam forever, is the event of Karbala. No mention of Karbala is complete without Hurr ibn Yazid Ar-Riyahi. He is an example for those who reflect upon his journey, his actions and his martyrdom. He encourages, inspires and motivates the believers through his actions in Karbala. 

Background

Hurr literally means a freeman in Arabic, and truly so he lived up to his name. 
Hurr Ibn Yazid Ar-Riyahi was the general of the Ummayad army dispatched from Kufa, (Iraq) to intercept Imam Al-Hussain (AS), the third infallible Imam. Ubaydullah ibn Ziyad, the newly appointed governor of Kufa issued the command to guard all entrances and exits to Kufa in order to intercept al-Hussain for an oath of allegiance to Yazid. Hurr was ordered along with his 1,000 soldiers to intercept Imam Hussain(AS) and his followers before they reached Kufa.

When he intercepted Imam Hussain (AS) at Dhu Hussam, Hurr and his men had ran out of water. The Imam(AS) ordered his companions to satiate Hurr and his army, including the cavalry. Hurr and his men offered their prayers with the Imam and listened to his sermons. However, on subsequent orders from the tyrant governor of Kufa, Ubaidullah Ibn Ziyad, Imam Hussain and his family were forced to encamp in Karbala. Hurr was of the notion that the Imam (AS) will not be killed in Karbala, he would somehow persuade him to go elsewhere. But he was perturbed when he realized that Umar Ibn Sa'ad who was sent by Ubaidullah had come with orders to kill Imam Hussain. On one hand was his position, family and wealth and on the other hand was the grandson of the Holy Prophet(PBUH&HP) and the son of Imam Ali (AS) and Lady Fatima (SA), supporting whom meant a certain death. These were the two options left for Hurr, just as the Holy Quran says:
 "Indeed We have guided him to the way, be he grateful or ungrateful." (76:3). 

What do we learn from Hurr?

Despite all odds, Hurr left the Army of Yazid, joined Imam Hussain (AS) and won the honor of being the first martyr of Karbala. All the glitter of the world, his power, rank, wealth and children did not stop him from joining his master Hussain(AS). 
Ashura and Karbala were not be bound by time or geographical location. Almost 14 centuries have passes by but human beings from different parts of the world, belonging to different races and religions continue to mourn for Imam Hussain(AS) and take inspiration from him and his mission.
Just as Karbala continues to inspire us, the magnanimous personality of Hurr continues to inspire and guide us. Hurr chose good over bad, truth over falsehood, hereafter over the transient world. If we claim to be followers and lovers of Imam Hussain(AS) we need to turn towards the Hussain of our time and follow the teachings of Imam Hussain(AS). Imam Hussain(AS) gave everything he had to protect and preserve the teachings of Islam and by helping Hussain(AS) in his cause, Hurr achieved this lofty position of being Imam Hussain's(AS) helper. Thus, if Hurr truly motivates us, we need to mend our ways and make ourselves capable of helping Imam Mahdi (AJ) the true inheritor of Imam Hussain's (AS) legacy.

The Hurr of Karbala teaches us that true love is incomplete without sacrifice. 

But, is the Hurr inside us ready to listen?
