Dear Sardar Ali Shravan,
When will you start studying the Qur'an?
5:6 O You who have chosen to be graced with belief! When you congregate for Salaat, wash your faces and your forearms, hands to the elbows. Lightly rub your heads and your feet to the ankles.
If you are in the post-coital state with your spouses, bathe your whole body. But, if you are ill or traveling, or coming from the privy, or are in the post-coital state and find no water, then observe dry ablution by touching clean dry soil and lightly rub your faces and hands. God does not wish to place any difficulty upon you, but to make you clean and to perfect His blessings upon you, that you may be grateful. [4:43. Wudhu = Ablution will help prepare mentally for congregational prayer. Tayammum = Dry ablution]
