SHAFAQNA – Allah (SWT) in Ayah 31 of Surah Al-A’araaf say: “O’ children of Adam, wear your beautiful clothes in every Salaat, and eat and drink but do not waste because God does not like wasters.” In Ayah 87 of Surah Ma’edah, Allah (SWT) warns the believers by saying: “O’ you who believe, do not consider as Haram those things which God has made Halal for you to use, do not exceed the boundaries as Allah (SWT) does not like those who exceed them.”
One of the most important religious commands is personal care and cleanliness. Washing hands and face, combing hair, using perfume, cutting short nails, wearing white and clean clothes are examples of the tradition of the Prophet (PBUH). It is appropriate that every Muslim follow the tradition of the Prophet (PBUH) and show that Islam is the religion of cleanliness and purity.
It is narrated from Imam Ali (AS) who said: The Prophet of Islam (PBUH) always used to comb his hair and most of the times by using water he straightened and combed his hair . Observing the cleanliness of the body, mouth and teeth are strictly emphasized in Islam. Basically acts such as ablution and Wudhu are among the most important ways of cleaning and purifying the body and the soul.
