Musnad Ahmad 1460

It was narrated that Sulaiman bin Abi ‘Abdullah said: I saw Sa"d bin Abi Waqqas who had caught a man hunting in the sanctuary (haram) of Madinah, which the Messenger of Allah (ﷺ) declared to be a sanctuary, and he stripped him of his garments. His master came and he [Sa"d] said: “The Messenger of Allah (ﷺ) declared this to be a sanctuary and said: “Whoever you see hunting anything in it, you may strip him of his belongings." I will not return a gift that the Messenger of Allah (ﷺ) gave to me, but if you wish I shall give you its price.” And on one occasion "Affan said: “If you want me to give you its price, I will give it to you.”
