One who frightens a Muslim

Sayyiduna Abu Hasan (may Allah be pleased with him), who had the honour of taking part in the Pledge of Aqabah and the Battle of Badr, narrates: Once we were sitting with the Prophet (peace and blessings be upon him).

The people said: "We have not seen them." He said: "They were right here." The Prophet (peace and blessings be upon him) said: "How can a believer be alarmed? How can he be alarmed?" The man said: "O Messenger of Allah, I only did it as a joke." The Prophet (peace and blessings be upon him) said: "How can a believer be alarmed?" He said this twice, or perhaps three times.
