Abu Dawud Book 8, Hadith Number 2681.

Chapter : Not known.

Narated By AbuAyyub al-Ansari : AbuDawud said: The narrators other than Sa’id reported from Ibn Wahb in this tradition: “(Killed him) with arrows in confinement.” When AbuAyyub al-Ansari was informed about it, he said: I heard the Apostle of Allah (PBUH) prohibiting to kill in confinement. By Him in Whose hands my soul is, if there were a hen, I would not kill it in confinement. AbdurRahman ibn Khalid ibn al-Walid was informed about it (the Prophet’s prohibition). He set four slaves free.
