Abu Salih al-Hanafi narrated this from one of the Companions of the Prophet (peace and blessings be upon him)
(the narrator says: I think that Companion is Sayyiduna Abdullah bin Umar, may Allah be pleased with them both). He said: I heard the Prophet (peace and blessings be upon him) say: "Whoever mutilates a living creature and then does not repent of that deed, Allah Almighty will mutilate him on the Day of Resurrection."
Ahmad, and al-Tabarani in al-Mu'jam al-Awsat, recorded it from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) without any doubt, and the narrators of Ahmad are thiqat (trustworthy).
