The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
Dawud :: Book 10 : Hadith 2032
Narrated Sa'd ibn AbuWaqqas:
Sulayman ibn AbuAbdullah said: I saw Sa'd ibn AbuWaqqas seized a man hunting in the sacred territory of Medina which the Apostle of Allah (peace_be_upon_him) had declared to be sacred. He took away his clothes from him. His patrons came to him and spoke to him about it, but he replied: The Apostle of Allah (peace_be_upon_him) declared this territory to be sacred, saying: If anyone catches someone hunting in it he should take away from him his clothes. So I shall not return to you a provision which the Apostle of Allah (peace_be_upon_him) has given me, but if you wish I shall pay you its price.
