Dog is one of the forbidden animals in Islam. Its meat is haram, and its saliva is one of the heaviest najis that needed to be avoided,
Allah SWT said:
“They ask you, [O Muhammad], what has been made lawful for them. Say, “Lawful for you are [all] good foods and [game caught by] what you have trained of hunting animals which you train as Allah has taught you. So eat of what they catch for you, and mention the name of Allah upon it, and fear Allah .” Indeed, Allah is swift in account.” (Al-Mai’dah:4)
The Prophet also has been reported to say:
“The Prophet is invited to enter houses and he accepted. At other times, he often declines the invitation. If asked why he said: “In the second house there is a dog while in the first house there is only a cat. And the cat is not a najis.” (Hadith Al-Hakim)
In Islam, a dog excrement is one of the heaviest najis that we need to clean in a more specific ways. And then how to cleanse the dog’s excrement on clothes? If you get licked by a dog, then its saliva is a najis that needed to be cleaned immediately.
From Abu Hurairah (rad):
إذا ولغ الكلب في إناء أحدكم ، فليرقه ، ثم ليغسله سبع مرات
“The Messenger of Allah (ﷺ) said: ‘If a dog licks the vessel of any one of you, let him throw (the contents) away and wash it seven times.'” (An-Nasa’i 335)
Imam Nawawi explained in his book “Al Majmu'”, that a splash of dust or soil is advised on the first rinse. If it is not possible, then it is alright to do it on one of the other rinse except the last one or the seventh rinse.
And therefore, clothes will not be dirty by dirt or dust for it will be cleansed on the last splash. Al-Irag said: “The Prophet especially said the vessels of you for it is the tools that usually got licked by dogs.”
According to the verse above, it is mandatory to wash our utensils or clothes seven times if it gets licked by dogs, one of them is done by dust or soil. It is the opinion of Abdullah bin Abbas, Abu Hurairah (rad), Muhammad bin Sirin, Thawus, etc.
And it also explained on:
لعاب الكلب نجس ، يجب غسل ما أصابه من إناء أو ثوب لقوله صلى الله عليه وسلم : (طَهُورُ إِنَاءِ أَحَدِكُمْ إِذَا وَلَغَ فِيهِ الْكَلْبُ أَنْ يَغْسِلَهُ سَبْعَ مَرَّاتٍ أُولَاهُنَّ بِالتُّرَابِ). والثياب إذا ألقيت في الماء الطهور وغسلت حتى زال أثر النجاسة عنها طهرت جميعا من نجاسة الكلب وغيره ، بشرط أن يتكرر غسلها من نجاسة الكلب سبع مرات ، تكون أولاهن بالتراب أو ما يقوم مقامه كالصابون والأشنان” انتهى
Al-Bukhaari and Muslim reported from Abu Hurayrah (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: If a dog licks the vessel of any one of you, let him throw away its contents, then wash it seven times. Muslim added: the first time with earth. Clothes are put into water and washed so it is free from the stain of najis, be purified. Whether the najis of dogs or others. However the requirement to clean dogs najis is by rinsing it for seven times, the first one with earth or anything that replace it such as soap or “asynaan”
According to the explanation above, it is safe for us to conclude that clothes that gets stained by dogs it is mandatory to clean it. However, if clothes get stained by the dog’s fur, then it is unnecessary to do the same routine as the heavy najis. You shall remove its fur from your clothes as how you do to other animals. It is for the fur of a dog is not the same as its saliva.
The Messenger of Allah (ﷺ) was asked about ghee, cheese, and wild donkeys:
الحلال ما أحل الله في كتابه. والحرام ماحرم الله في كتابه. وما سكت عنه فهو عفا عنه
“He said: ‘What is lawful is that which Allah has permitted, in His Book and what is unlawful is that which Allah has forbidden in His Book. He remained silent about is what is pardoned.’” (Al-Farisi, 3367)
That is explained regarding how to cleanse the dog’s excrement on clothes and its verses. though we have learned the way of how to cleanse it, it does not mean we shall be unaware of the weight of it. Allah SWT bless all of us. Aaamiin.
