Wuduu (Ablution) is so important even in terms of health because it cleans the organs that are exposed to dirtiness and that are always in contact with things outside like hands, face, mouth, teeth, nose, head and feet. The ways through which microbes could penetrate the body are cleaned at least five times a day Alhamdulillah; thus, many diseases are prevented; the nervous system and the circulatory system of the body then functions better.
Wuduu actually eliminates anger and calms the spirit. Therefore, the Prophet (sallallahu alaihi wasallam) advised a person who becomes angry to make wuduu. (Abu Dawud, Adab, 3; Musnad, 4/226) Wuduu is a spiritual weapon of a believer and a spiritual shield against invisible dangers. Alhamdulillah.
A Muslim who makes wuduu is purified and cleaned from both material and spiritual impurities. His sins are washed away as he washes an organ; it is stated that each organ of wuduu will shine brightly on the Day of Resurrection.
“When a Muslim who makes wuduu rinses his mouth and nose, the sins committed by his mouth and nose are washed away. When he washes his face, his sins are washed away from his face and even between his two eyelids. When he wipes his head, his sins are washed away from his head and even from his ears. When he washes his feet, the sins committed by his feet are washed away from his feet and even between his nails. Thus, that person is purified from his sins and faults.” (Ibn Majah, Taharah, 6; Muslim, Taharah, 32; Nasai, Taharah, 108). AlhamdulilLah for HIS guidance. May ALLAH keep guiding us all and protect us from any satanic influences. Aameen.
