"Although most modern dogs are kept as pets, there are still a tremendous number of ways in which dogs can and do assist humans, and more uses are found for them every year" [1]. This animal is used in many activities such as rescuing, herding, sledding, hunting, guarding, tracking, and Human Remains Detection.There are also war and police dogs, which all indicate the versatility of this animal. But in Islam, there are some restrictions regarding the relationship with this useful creature.The term "impure" (Najis) in Islamic jurisprudence refers to things that are avoided because of the intensity of filth in them, one of which is dogs. The religion of Islam has warned Muslims to keep dogs “as pets” since they are deemed dirty. Now, let’s see why:

The Impurity of Dogs

Unless properly trained, dogs will defecate and urinate where ever they please; they also slobber everywhere, which doctors say is the cause of many diseases and infections.

Even though the level of awareness about the hazards of having a dog has increased among dog owners and necessary precautions about keeping it as a pet have been taken by them, dog bites continue to be a public health problem in the USA [1].

Doctors always warn about diseases we may catch from dogs: “Hookworms and roundworms (Ancylostoma and Ascaris) are common nematodes of dogs. When a human accidentally eats something contaminated with worm eggs from a pet’s stool, the eggs hatch in the intestines and begin migrating throughout that person’s body” [2].

From the viewpoint of Islam, when we speak about the impurity of the dog, we mean its "outward" filth and all its organs including skin, flesh, and hair. So, everything is considered as "impure" in contact with a wet dog or vice versa (a wet thing in contact with a dog). Almost all Muslim scholars do not doubt that dogs are impure animals. There are many narrations (Hadiths) about the impurity of dogs in authentic narration books, including:

“Allah has not created a creature more impure than dogs” [3].
“If your clothes get dampened by a dog, then you must wash them” [4].

The Fidelity of Dogs

Perhaps, one of the reasons for Islam to prohibit Muslims from keeping dogs as pets [3] is due to the high fidelity of these animals. The bond between dogs and their owners has an important impact on family relationships in a way that the dog owner may forget his family members and relatives, adore his/her pet, and neglect God’s worship as well.

It has been reported that “More and more US women are forgoing motherhood and getting their maternal kicks by owning handbag-size canines” [5].

Trained dogs in Islam

There are possibly two reasons for a person to have a dog: affection for the animal or security.

In the first case, the dog will most probably live with you in your house, which is prohibited according to Islamic law.

And in the second one, the case of security, the dog is mostly kept on the periphery of your house or property; like the dogs that are held for hunting, guarding livestock, crops, and for guarding houses, etc. These dogs are called trained dogs (Kalb-e-Moallam) in Islam and the rules regarding them are different from the ones for the other kinds of dogs.

There are exceptions to them, and they are not considered “impure” because of their skills. This fact has been mentioned in the Holy Quran directly: “As for what you have taught hunting dogs [to catch], teaching them out of what Allah has taught you, eat of what they catch for you and mention Allah’s Name over it …” (5:4)

Do Muslims hate dogs?

But do Muslims consider dogs as filthy and useless creatures? No. because these animals are also creatures of God. Similarly, despite its many benefits and its importance for human life, human blood is also regarded as impure in Islamic teachings.

In other words, dogs’ impurity does not deny the existence of their good features such as loyalty or innocence, just as the impurity of human urine, feces, and blood has nothing to do with his/her humanity.

On the other hand, Islam has proposed very detailed rights for all kinds of animals including dogs, which a Muslim must respect and observe. For example, one day when Imam Hussain (AS) saw his servant sharing his food with Imam’s garden guard dog, he highly admired the servant for his kind behavior, rewarded him with 1000 Dinars and even donated the garden to him just for observing the right of a dog [6].

Is that all?

The words mentioned above reveal the Islamic view of dogs. But is that all? Have we successfully and thoroughly looked into it to reach firm ideas about dogs?

To tell you the truth, we are not always able to understand the essence of Islamic rules and guidelines. More importantly, Muslims have learned to fully observe the practices ordained by God because they believe these practices are best for them, just like following the instructions that come with the electronic devices without questioning them.

If God, the Prophet (PBUH&HP), and infallible Imams (AS) prohibit specific practices, it is definitely because they have certain harmful effects on us that may or may not be immediate or measurable.

“…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)

In a nutshell

It is permissible to keep dogs for security purposes in Islam, but you cannot let them inside your house. However, this does not mean we can harm dogs or hate them, Not at all; on the contrary, we should always be compassionate with dogs as much as we should be with any other living kind.

Nowadays, being surrounded by different types of media products, one may be bewildered if all these movies and animations are lawful (Halal) or not. We might found many of them to have some contradictions with Islamic rules.
The fact is that many issues did not exist 1400 years ago, and therefore, there is no direct mention of them in the Quran or narrations of the Prophet (PBUH&HP). 

However, Islam is not a contextual religion that was only suitable for people of its own time. Instead, it is a universal religion that can be a guideline for all human beings, anywhere and anytime. Thus, we should be able to find out the Islamic viewpoint about watching movies and animations; which, indeed, have a central role in most of our lives these days.

The Fundamental Frameworks Regarding Watching Movies

Although there is no direct mention of movies in the Quran, Islam has provided us with some fundamental frameworks that describe the freedoms and redlines of the religion. Those are the Islamic laws that are extracted from the Quran and narrations. Having those fundamental frameworks in mind, we can always have a criterion to distinguish the lawfulness or forbiddance of any new issue that may arise in our individual or social life.

Now, let’s revise some of these fundamental frameworks to find out if watching movies and animations are forbidden in Islam or not.

Rule number 1

There is a verse in the Quran that says: “Say: Who has forbidden the adornment of Allah which He has brought forth for His servants, and the good things of [His] provision?’ Say, ‘These are for the faithful in the life of this world, and exclusively for them on the Day of Resurrection.’ Thus do We elaborate the signs for a people who have knowledge.” (7: 32)

The verse shows that there have been people who prevented themselves from even lawful adornments of this world. Therefore, Allah, by using the imperative word “say,” tells his Prophet to ask people ‘based on what religion they are forbidding the blessings of Allah to themselves.’ 

Based on this verse, the blessings in this world have been created for faithful people, while the unbelievers can also use them. Byte they are merely for goof believers in heaven.

Rule number 2

By reading rule number 1, some may think that Allah is not taking it too harshly, and therefore, everything is lawful for us. But since Allah knows better how we may misuse His words, He quickly continues with the following verse: 
“Say, ‘My Lord has only forbidden indecencies, the outward among them and the inward ones, and sin and undue aggression, and that you should ascribe to Allah partners for which He has not sent down any authority, and that you should attribute to Allah what you do not know.’” (7: 33)

Therefore, any indecencies and wrongdoing that may in any way cause harm to an individual or the society are forbidden in Islam. 

There are so many other verses that can help us find our answer in terms of watching movies. However, the two above verses can be the criteria to help us distinguish any Lawful (Halal) and unlawful in Islam. 

Analysis

Let’s choose a movie in mind and use the following questions as our criterion to distinguish if they are Lawful (Halal) or not.

1- It teaches me a lot. 

2- It motivates me to be a better person and find better behavior and habits in life. 

3- It gives me peace of mind.

4- It contains bad words that may remain in my mind. 

5- It contains violence that is not motivating in the right way, but will wake my aggression. 

6- It contains sexual scenes.

7- It gives me a nihilistic feeling.

Numbers 1, 2, and 3 are the manifestation of adornments and blessings of Allah, while numbers 4, 5, 6 and 7 are indecencies and wrongdoing. 

The above were only some examples, but if you have more criteria based on the Quranic teachings in mind, you may find it easier to distinguish between right and wrong. 

Conclusion

Watching movies and animations are not forbidden (Haram) in Islam if they don’t contain any prohibited elements. Muslims are allowed to watch, enjoy, and learn from movies that contain no indecencies and has no harm for any individual or society. 

However, being a Muslim means that one has the aim of improving to the highest levels of faith. Thus, one should keep in mind the verse of the Quran that says: “The life of the world is nothing but play and diversion, and the abode of the Hereafter is surely better for those who are Godwary. Do you not exercise your reason?” (6: 32)

Therefore, even if the movies and animation are lawful (halal) to watch, we should make sure not to waste our time watching too much of them and neglect our main tasks in life. 
“… and eat and drink, but do not waste; indeed, He does not like the wasteful.” (7: 31)
