The month of Ramadhan, wherein was revealed the Koran, for a guidance to men, and for manifestations of guidance, and for a Discrimination. And he amongst you who beholds this month then let him fast it; but he who is sick or on a journey, then another number of days;- God desires for you what is easy, and desires not for you what is difficult,- that ye may complete the number, and say, 'Great is God,' for that He has guided you; haply ye may give thanks.
