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?

Nowadays, pets are inseparable parts of people’s lives. In the United States, for example, over 60% of families have pets. Some have dogs, cats, while others keep fish, turtles, birds, rabbits, horses, sheep, pigs, or chickens. No one knows for sure when the first animals were domesticated, but according to history, humans have always developed close associations with animals. Although early humans might have first sought to domesticate animals as living tools, other benefits of animals caused humans to keep pets, too. Muslims can also exploit animals taking into account some considerations stated below.

Animals from The Islamic Point of View

Islam has never been indifferent to animals. The proofs are verses of the Quran, Sunnah, and sayings of the Imams (AS) which strongly exhort Muslims to treat animals and birds with compassion, not to abuse them, and repeatedly blame cruelty towards them.

In a narration, Prophet Muhammad (PBUH&HP) enumerates six rights for an animal over its owner, of which are: “he should not burden it with a load that it cannot bear, he should not hit the animal except when it truly deserves”, etc. [1].  

Hence, hitting a dog in the face or body as punishment and making it obedient through fear, putting a heavy load on a camel or a horse, providing little food for a cat, and putting a canary in a small cage are all blamed in Islam. It is also quoted from the Prophet (PBUH&HP) that God forgave a prostitute who saved a thirsty dog from death by drawing up some water from a well using her shoes [2]. Also, According to the Quran, all living and non-living creatures are made by Allah [i], and He loves all animals; so should do humans.

Keep pets: Allowed or Not?

In Islamic teachings, there is nothing wrong with keeping animals and it is even recommended in some cases; except for some animals that Islamic conditions or prohibition on keeping them should be observed. Besides, keeping some animals such as roosters, camels, sheep, horses, cats, and pigeons is highly recommended [3].

In other words, keeping permissible animals is allowed, and in some cases, it brings blessing to its owner [4]. But, this should be under certain circumstances, such as: treating and feeding pets properly, having enough space to accommodate them, considering the hygienic requirements of both the animal and its owner, and respecting neighbors’ rights.

For accommodating an animal at home, a proper separate shelter must be provided, based on the needs and the nature of the animal. For a bird, for example, a comfortable cage indoors suffices, but a camel or a sheep must be kept outdoors! In this regard, apart from the hygienic points that should be taken into account, the excrement and urine of some birds and animals are impure (Najis), hence, keeping them indoors needs attention [5].

What is encouraged in Islam is keeping domesticated animals that need humans to protect and feed them, or wild animals which require protection; otherwise it should be avoided, especially if keeping the animal at home causes harm to it [5].

Why Keeping Certain Pets Is Recommended in Islam?

A review of the Islamic narrations reveals that the emphasis on keeping pets is because of the benefits and the blessings that certain animals bring to their owners and saving them and their families from disasters. Having camels, horses and sheep were advised in the past because of their role in the economy of the family, transportation, and defense. And nowadays, many people around the world consume the products obtained from sheep, and some still use horses and camels for farm work and transport in some areas.

In some sayings keeping a rooster, pigeon, sheep, and cat is named among the ways of drawing sustenance and benefits [6]. Another advantage of having pets is that some animals warn humans in case of danger, they clean up their surroundings from vermin and prevent waste [3].

It is also essential to know that respecting the animals’ rights is of paramount importance in Islam and is explicitly stated in Islamic teachings. This equally applies to both animals permitted and forbidden to be kept by Muslims. This prevents from treating animals cruelly, neglecting them, over-working or over-loading animals (as stated above), and hunting them for sport.

Which animals are forbidden to keep?

It was said that keeping animals is recommended in Islam, but not all of them; like dogs and especially pigs. Since dogs are considered impure (Najis) and humans are susceptible to catch a disease from them, Muslims are advised against keeping them [3]. Nevertheless, there is nothing in Islam that states to hate dogs or harm them. On the contrary, feeding dogs (even stray dogs) and watering them are reported in Sunnah and the conduct of the Imams (AS) [7]. It is also permitted to keep dogs where they assist humans and are kept outdoors [3].

But about pigs, as there is no benefit in keeping them and as they are impure (Najis), Muslims are forbidden to keep them [5].
