It is narrated from Ibn Abi Laila (may Allah be pleased with him) that several companions (may Allah be pleased with them) told us that once they were traveling with the Noble Prophet (peace and blessings be upon him). One of them fell asleep, and another man quietly approached him and took his arrow. When that man woke up from his sleep, he became frightened. People began to laugh at his condition. The Noble Prophet (peace and blessings be upon him) asked the people why they were laughing. The people said, "It is nothing, we just took his arrow, and he became frightened." The Noble Prophet (peace and blessings be upon him) said, "It is not lawful for a Muslim to frighten another Muslim."
