Shurahbil bin Sa'd (may Allah have mercy on him) narrates that Sayyiduna Zayd bin Thabit (may Allah be pleased with him) found him having caught a bird (called a nahas). He said: He took it from me and set it free, and struck me, and said: O enemy of Allah! Do you not know that the Messenger of Allah (peace and blessings be upon him) declared the area between the two stony tracts of Madinah sacred? Meaning the area between its two lava fields.
