“The Messenger of Allah ﷺ commanded that dogs be killed.” (Using translation from Ibn Mājah 3202)  

«أَمَرَ رَسُولُ اللَّهِ ﷺ بِقَتْلِ الْكِلَابِ»  

The Prophet ﷺ said: Were dogs not a species of creature I should command that they all be killed; but kill every pure black one. (Using translation from Abū Dāʾūd 2845)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَوْلَا أَنَّ الْكِلَابَ أُمَّةٌ مِنَ الْأُمَمِ لَأَمَرْتُ بِقَتْلِهَا كُلِّهَا وَلَكِنِ اقْتُلُوا مِنْهَا كُلَّ أَسْوَدَ بَهِيمٍ» قَالَ سَعِيدُ بْنُ عَامِرٍ «الْبَهِيمُ الْأَسْوَدُ كُلُّهُ»
