It is narrated from Sayyiduna Sulayman bin Surad (may Allah be pleased with him) that a Bedouin prayed with the Prophet (peace and blessings be upon him) while he had a quiver with him, and someone took his quiver. When the Prophet (peace and blessings be upon him) concluded the prayer with the salam, the Bedouin said: "Where is my quiver?" It seemed that some of the people laughed, whereupon the Prophet (peace and blessings be upon him) said: "Whoever believes in Allah and the Last Day must not frighten a Muslim."
