Abu Dawud Book 4, Hadith Number 2027.

Narated By Az-Zubayr : When we came along with the Apostle of Allah (PBUH) from Liyyah and we were beside the lote tree, the Apostle of Allah (PBUH) stopped at the end of al-Qarn al-Aswad opposite to it. He then looked at Nakhb or at its valley. He stopped and all the people stopped. He then said: The game of Wajj and its thorny trees are unlawful made unlawful for Allah. This was before he alighted at at-Ta’if and its fortress for Thaqif.
