Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "When a fly falls into the vessel of any one of you, he should immerse it completely, for one of its wings has disease and the other has cure. It tries to protect itself with the wing that has the disease, so a person should immerse it completely and then take it out."
(Imam Ibn Hibban, may Allah have mercy on him, says:) The Arabs use this word for both immersing and lifting, because the word 'Ittiqaa' is used for both meanings.
