Dogs in Islam

Several hadiths in the two most authoritative Sunni collections — Sahih Muslim and Sunan Abu Dawood — deal extensively with dogs: recording a decree by Muhammad to kill them, explaining that black dogs are devils, and ruling that a black dog passing in front of a man during prayer nullifies the prayer. Each hadith is shown with its original Arabic text, an English translation, a link to the authoritative source, and a neutral, factual explanation.


Gabriel's Refusal and the Decree to Kill Dogs

Two parallel narrations — one from Maimunah (a wife of the Prophet) recorded in Sahih Muslim, and one from Ibn Abbas recorded in Sunan Abu Dawood — report the same event: the angel Gabriel fails to appear as promised, Muhammad discovers a puppy under his bed, removes it, and Gabriel then explains that angels cannot enter a home containing a dog or a picture. On the strength of this explanation, Muhammad orders all dogs in Medina to be killed.

Sahih Muslim 2105 — Gabriel Refuses House with Dog; Dogs Ordered Killed

أَصْبَحَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمًا كَئِيبًا فَقَالَتْ مَيْمُونَةُ يَا رَسُولَ اللَّهِ لَقَدِ اسْتَنْكَرْتُ هَيْئَتَكَ مُنْذُ الْيَوْمِ قَالَ وَعَدَنِي جِبْرِيلُ أَنْ يَلْقَانِيَ اللَّيْلَةَ فَلَمْ يَفْعَلْ ثُمَّ ذَكَرَ جَرْوَ كَلْبٍ كَانَ تَحْتَ فُسْطَاطٍ لَنَا فَأَمَرَ بِهِ فَأُخْرِجَ ثُمَّ أَخَذَ بِيَدِهِ مَاءً فَرَشَّ بِهِ مَكَانَهُ فَلَمَّا كَانَ الْمَسَاءُ لَقِيَهُ جِبْرِيلُ فَعَاتَبَهُ فَقَالَ وَعَدْتَنِي أَنْ تَلْقَانِي أَمْسِ قَالَ أَجَلْ وَلَكِنَّا لَا نَدْخُلُ بَيْتًا فِيهِ كَلْبٌ وَلَا صُورَةٌ فَأَصْبَحَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَمَرَ بِقَتْلِ الْكِلَابِ

Maimunah reported that one morning Allah's Messenger was silent with grief. Maimunah said: Allah's Messenger, I find a change in your mood today. Allah's Messenger said: Gabriel had promised me that he would meet me tonight, but he did not meet me. By Allah, he never broke his promises, and Allah's Messenger spent the day in this sad [mood]. Then it occurred to him that there had been a puppy under their cot. He commanded that it was turned out. He then took some water in his hand and sprinkled it at that place. When it was evening, Gabriel met him, and he said to him: you promised me that you would meet me the previous night. He said: Yes, but we do not enter a house in which there is a dog or a picture. Then on that very morning, Muhammad commanded the killing of the dogs until he announced that the dog kept for the orchards should also be killed, but he spared the dog meant for the protection of extensive fields.

— Sahih Muslim, Volume 5, Book 24 (USC-MSA numbering)

This narration presents the occasion for Muhammad's decree to kill dogs as a personal one: the angel Gabriel refused to visit because a puppy was present in the household. The decree that followed was broad — kill all dogs in Medina, including those guarding orchards — with only dogs guarding large fields exempted. The stated theological rationale is that angels cannot coexist with dogs (or pictures/images) in a dwelling.

From an ethical standpoint, the hadith records a mass extermination of animals motivated not by disease control or public safety but by the requirements of angelic visitation to one individual. Dogs are a common domestic animal throughout the world; many Islamic scholars today hold them to be ritually impure (najis), a ruling derived substantially from hadiths such as this one.

Sunan Abu Dawood 4157 — Gabriel Refuses House with Dog (Parallel Narration)

إِنَّ جِبْرِيلَ عَلَيْهِ السَّلاَمُ كَانَ وَعَدَنِي أَنْ يَلْقَانِيَ اللَّيْلَةَ فَلَمْ يَلْقَنِي ثُمَّ وَقَعَ فِي نَفْسِهِ جَرْوُ كَلْبٍ تَحْتَ بِسَاطٍ لَنَا فَأَمَرَ بِهِ فَأُخْرِجَ ثُمَّ أَخَذَ بِيَدِهِ مَاءً فَنَضَحَ بِهِ مَكَانَهُ فَلَمَّا لَقِيَهُ جِبْرِيلُ عَلَيْهِ السَّلاَمُ قَالَ إِنَّا لاَ نَدْخُلُ بَيْتًا فِيهِ كَلْبٌ وَلاَ صُورَةٌ فَأَصْبَحَ النَّبِيُّ صلى الله عليه وسلم فَأَمَرَ بِقَتْلِ الْكِلاَبِ حَتَّى إِنَّهُ لَيَأْمُرُ بِقَتْلِ كَلْبِ الْحَائِطِ الصَّغِيرِ وَيَتْرُكُ كَلْبَ الْحَائِطِ الْكَبِيرِ

Narrated Ibn Abbas: Maimunah, wife of the Prophet reported him as saying: Gabriel promised to visit me last night, but he did not visit me. Then it occurred to him that there was a pup under his bed. So he ordered and it was turned out. He then got water in his hand and sprinkled it on its place. When Gabriel met him, he said: We do not enter a house which contains a dog or a picture. When the morning came, the Prophet ordered to kill dogs. He ordered to kill the dog which guarded a small orchard, and left the dog which guarded the big orchard.

— Sunan Abu Dawood, Book 34, Hadith 138

This is a parallel narration of the same event from a different chain of transmission (Ibn Abbas rather than Maimunah directly). It corroborates the Sahih Muslim version: Gabriel's refusal → discovery of the puppy → its removal → Gabriel's explanation → mass killing of dogs. The hadith is graded Sahih (authentic) by al-Albani.

The practical result encoded in this and other dog hadiths became a significant part of Islamic jurisprudence. Four of the five major Sunni legal schools (Maliki, Shafi'i, Hanbali, and a minority Hanafi position) classify dogs as ritually impure (najis al-'ayn), requiring ritual washing if a dog licks a vessel or a person's body. This ruling has no parallel in other Abrahamic traditions and distinguishes Islam's treatment of dogs sharply from both Judaism (which does not classify dogs as inherently impure) and Christianity.


The Black Dog as a Devil

Two further hadiths — one from Sahih Muslim, one from Sunan Abu Dawood — address the specific status of black dogs. Both narrations link black dogs to the devil (shaytan), with one adding the ruling that a black dog passing in front of a man at prayer invalidates that prayer.

Sahih Muslim 510a — Black Dog is a Devil; Breaks Prayer

إِذَا قَامَ أَحَدُكُمْ يُصَلِّي فَإِنَّهُ يَسْتُرُهُ إِذَا كَانَ بَيْنَ يَدَيْهِ مِثْلُ آخِرَةِ الرَّحْلِ فَإِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ مِثْلُ آخِرَةِ الرَّحْلِ فَإِنَّهُ يَقْطَعُ صَلاَتَهُ الْحِمَارُ وَالْمَرْأَةُ وَالْكَلْبُ الأَسْوَدُ قُلْتُ يَا أَبَا ذَرٍّ مَا بَالُ الْكَلْبِ الأَسْوَدِ مِنَ الْكَلْبِ الأَحْمَرِ مِنَ الْكَلْبِ الأَصْفَرِ قَالَ يَا ابْنَ أَخِي سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم كَمَا سَأَلْتَنِي فَقَالَ الْكَلْبُ الأَسْوَدُ شَيْطَانٌ

Abu Dharr reported: The Messenger of Allah said: When any one of you stands for prayer and there is a thing before him equal to the back of the saddle that covers him and in case there is not before him (a thing) equal to the back of the saddle, his prayer would be cut off by (passing of) an ass, woman, and black dog. I said: O Abu Dharr, what feature is there in a black dog which distinguishes it from the red dog and the yellow dog? He said: O son of my brother, I asked the Messenger of Allah as you are asking me, and he said: The black dog is a devil.

— Sahih Muslim, Book 4, Hadith 1032 (USC-MSA numbering)

This hadith contains two notable rulings. First, it equates three things that "break" (cut off / invalidate) a man's prayer if they pass in front of him without a barrier: a donkey, a woman, and a black dog. The grouping of a woman with a donkey and a devil-dog as equal prayer-breaking entities reflects the hadith literature's broader treatment of women as religiously disruptive to male worship — a view that has been debated within Islamic scholarship itself, with some scholars arguing it applies only to pre-pubescent girls or specific contexts.

Second, it identifies the black dog specifically as a shaytan (devil). This is presented not as a metaphor but as a direct statement: "The black dog is a devil." No equivalent theological status is ascribed to dogs of other colours, making this the basis for the stronger prohibition on keeping black dogs in particular within some classical legal opinions.

Sunan Abu Dawood 2840 — Kill Dogs, Confine to Black Ones (Devils)

أَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِقَتْلِ الْكِلَابِ حَتَّى إِنَّ الْمَرْأَةَ تَجِيءُ بِكَلْبِهَا مِنَ الْبَادِيَةِ فَيُقْتَلُ ثُمَّ نَهَى عَنْ قَتْلِهَا وَقَالَ عَلَيْكُمْ بِالأَسْوَدِ الْبَهِيمِ ذِي النُّقْطَتَيْنِ فَإِنَّهُ شَيْطَانٌ

Narrated Jabir ibn Abdullah: The Prophet of Allah ordered to kill dogs, and we were even killing a dog which a woman brought with her from the desert. Afterwards he forbade to kill them, saying: Confine yourselves to the type which is black.

— Sunan Abu Dawood, Book 16, Hadith 2840 (USC-MSA numbering)

This narration records a revision to the earlier decree: after an initial broad command to kill all dogs — applied even to a woman's travelling companion — the order was narrowed to black dogs specifically. The reason given elsewhere in the hadith corpus (including Muslim 510a above) is that black dogs are devils. The instruction to kill black dogs because they are devils presents an empirical claim about the nature of a common animal that is not testable or verifiable.

Taken together, the dog hadiths establish a pattern: dogs (especially black ones) are theologically dangerous, associated with the devil, capable of preventing angelic visitation, capable of nullifying prayer, and subject to extermination. This stands in contrast to the Quran itself, which mentions dogs neutrally — the Companions of the Cave had a dog (18:18), and hunting dogs are permitted (5:4) — suggesting that the harshest anti-dog rulings derive from prophetic tradition rather than Quranic text.
