The Messenger of Allah ﷺ said regarding snakes, "We have not been at peace with them since we declared war on them. Whoever spares them out of fear is not one of us."
قال رسول الله ﷺ للحيات: ما سالمناهن منذ حاربناهن، فمن تركهن خيفتهن فليس منا.
Tahawi related it in Sharh Mushkil (1339) from Bakkar (that is, Ibn Qutayba), who said, Abu Dawud (that is, Tayalisi) narrated to us, Zaida bin Qudama narrated to us, from Mansur, from Abdullah bin Mura, from Masruq, from Abdullah bin Masud, and he mentioned something similar to the hadith of Abu Hurairah. That is, Tahawi did not state the wording of Ibn Masud's hadith, but simply referred back to the wording of Abu Hurairah's hadith mentioned just before it. This is a sahih chain of transmission.Abu Dawud (5249) and Nasai (516) both related it through Sharik, from Abu Ishaq, from Qasim bin Abdul-Rahman, from his father, from Ibn Masud, who said, the Messenger of Allah ﷺ said, "Kill all snakes, and whoever fears their vengeance is not of me."Sharik is Sharik bin Abdullah Nakhai, the judge, who has poor memory, and Qasim's father, Abdul-Rahman bin Abdullah bin Masud, heard only four hadiths from his own father, and this is not one of them. The meanings of the two wordings are close to each other.
