Hazrat Abu Saeed Khudri (may Allah be pleased with him) narrates that once Hazrat Siddiq Akbar (may Allah be pleased with him) came to the service of the Prophet (peace and blessings be upon him) and said, "O Messenger of Allah! I passed by a certain place where a man was praying with great humility and devotion in an excellent manner." The Prophet (peace and blessings be upon him) said, "Go and kill him." Hazrat Siddiq Akbar went, but when he saw him in the same previous state, killing him became burdensome for him, so he returned to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) then said to Hazrat Umar (may Allah be pleased with him), "You go and kill him." He went and also saw him in the same state as Hazrat Siddiq Akbar had seen, so killing him also became burdensome for him, and he too returned and said, "O Messenger of Allah! I saw him praying with such humility that I did not like to kill him." Then the Prophet (peace and blessings be upon him) sent Hazrat Ali (may Allah be pleased with him) and said, "You go and kill him." He went but did not find that man anywhere. He returned and said, "O Messenger of Allah! I did not find that man." The Prophet (peace and blessings be upon him) said, "He and his companions will recite the Qur'an, but it will not go beyond their throats, and they will leave the religion just as an arrow leaves the prey and does not return to it, until the arrow returns to its quiver. Kill this worst of creatures."
