It is narrated from Sayyiduna Zayd bin Thabit al-Ansari (may Allah be pleased with him) that he saw some boys who had cornered a fox, so he drove them away from it.
Imam Malik (may Allah have mercy on him) said: I believe he said: "Is this done in the sanctuary (haram) of the Messenger of Allah (peace and blessings be upon him) (Madinah)?"
