Praise be to Allah,
[Muhammad] ibn Abu ‘Adiyy narrated to us from Humayd [at-Taweel] from Arras ibn Maalik who said,
“Some men from the tribe of Uraynah embraced Islam, but they fell sick [as Madeenah climate did not suit them], so Allah’s Messenger (PBUH) said to them, ‘Go out to some camels of ours and drink their milk.’ (Humayd said that Qataadah added, from Anas, ‘and their urine.’) So they did that, but when they recovered, they reverted to disbelief, killed the herdsman of Allah’s Messenger (PBUH) who was a believer (or maybe he said a Muslim), drove away the camels of Allah’s Messenger and fled after committing this heinous act. Allah’s Messenger (PBUH) sent some men in their pursuit and they caught them and brought them back. Then he [ordered that] their hands and feet be cut off and their eyes are gauged out and that they are left in al-Harrah until they died.”
(Musnad Ahmad, Vol. 3, p. 107. The isnaad of this hadeeth is Saheeh according to the conditions set by al-Bukhaaree and Muslim.)
Note:
Al-Harrah is a well-known rocky place in Madeenah covered with black stones
