The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
Dawud :: Book 10 : Hadith 2027
Narrated Az-Zubayr:
When we came along with the Apostle of Allah (peace_be_upon_him) from Liyyah and we were beside the lote tree, the Apostle of Allah (peace_be_upon_him) 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.
