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?

Although one of the most joyful amusements that we usually choose, is to grab some chicken and meat from a supermarket or a Halal butcher and go out to the parks for a barbeque day, many of us have never thought about killing an animal and then barbecuing it.

Has it ever happened to you to be stuck in a village and have no access to butchers? Those of us who are more adventurous may have experienced camping in nature or visiting outlying villages. In such situations usually making a fire and roasting chicken or beef gives us the exciting sense of early humans. But who would be the one to kill that chicken, sheep, or cow and make it Islamically lawful (Halal)?

In this short text, I am going to provide you with a guideline of how to slaughter an animal according to Islamic law. But before starting on the Islamic slaughtering guideline, I know that you may have a bad feeling about killing animals, (as if other meats that we buy from butchers or supermarkets have been flourished in jungles beside mushrooms!!).

Or that many animal rights activists may condemn us for the Islamic slaughtering of animals. Therefore I would shortly argue if the Islamic way of slaughtering animals is a humane act or not?

Is slaughtering humane?

Eating meat has been naturally and instinctively downloaded in human beings! Our body has been created in a way to digest both meat and vegetables. That is why PKU is known as an inborn error of metabolism that causes an amino acid known as phenylalanine to build up in the blood because the phenylalanine hydroxylase (PAH) enzyme is either missing or not working properly [1]. People who suffer from PKU must live vegan as they lack this metabolism system.

God has created us meat-eaters and has permitted us to eat meat (but those that he has named forbidden (Haram)). Therefore having created human beings, the environment, and the animals, God knows best how nature's life-cycle must run.

Animals obey the rules of this cycle instinctively. However, having a quick search in the Quran and study the verses about food and drink, one can realize that opposing to slaughter or avoiding to eat animals is not something new that belongs to this century. “Why should you not eat that over which Allah’s Name has been mentioned, while He has already elaborated for you whatever He has forbidden you, excepting what you may be compelled to [eat in an emergency]? Indeed many mislead [others] by their fancies, without any knowledge. Indeed your Lord knows best the transgressors.” (6:119)

The Islamic slaughter: Rules and rituals

Now imagine we are in a far-away village, gathering with a group of friends. Of course, there are no butchers, nor a supermarket from which we can buy food. But there is a beautiful white lamb grazing in the field. How does it become lawful (Halal) to roast?

First of all, we have to buy it from the owner.

Don’t forget that the animal must be Halal-meated [2].

It is recommended to water the animal before the slaughter and do the slaughter job in a way that the animal feels the minimum pain and distress. And it is detestable (Makruh) to slaughter the animal in a place where other animals can see. It is also detestable (Makruh) to slaughter that animal that one has brought up and has an emotional connection to it [3].

Then we have to make sure that we follow the rules as below:

It must be facing the holy Kaaba (Qibla) when slaughtered.
The person performing the slaughter must mention the name of Allah as he slaughters the animal.
The slaughtering must be done with sharp metal so that the animal does not suffer much, and it happens as quickly as possible.
It must be slaughtered with a specific method in which the four main veins (the throat, windpipe, and blood vessels) are cut, without cutting the spinal cord.
The animal must show some sign of movement after being slaughtered, especially if there was some doubt whether the animal was alive before being slaughtered.
There must be a natural emission of blood from the animal after the act of slaughtering[i] [4].

Benefits of Islamic Slaughtering

As Islamic slaughtering is taken from the Quran and Prophet’s (PBUH&HP) conduct, it is known to be the best way of killing an animal in which it feels the least pain. Also, there are many scientific reasons behind this method of slaughter.

For example, the blood being drained entirely before the head is removed causes the emission of most of the blood which would serve as a suitable culture medium for microorganisms. Or for example, it is said in Islamic law that the spinal cord must not be cut, and the scientific reason found for this rule is that the nerve fibers to the heart could be damaged during the process causing cardiac arrest, stagnating the blood in the blood vessels [6].

There are some scientific explanations found to justify the fact that Islamic slaughtering is the best way of slaughtering. However, there are still many scientific and spiritual reasons that we are yet aware of. It is NOT impossible to find scientific reasons for God’s orders and prohibitions, but it is always easier to trust Him and obey His rulings for a more profitable life.

Notes: 
[i] It is permitted to stun the animal before slaughtering as it causes less pain and distress for it. However, the animal must be alive after stunning [5].
