In the Name of Allah, The Most Gracious, Most Merciful

Allah prevents you from eating and drinking, namely He prevents you in Ramadan from what is lawful and available to you in the other months of the year, so is it rational that you refrain from what is lawful, but then you commit sins? Hence, Ramadan strengthens the will of the believer since he leaves food and drink. Furthermore, will he lie? This is impossible! Will he feast his eyes on a woman who is not lawful to him? This is impossible! Will he abandon Salah? This is impossible! 
We leave food and drink as if the purpose of this month is to strengthen our will in order to obey Allah. Let us call an intensive course for thirty days. 
 

Praise be to Allah, the Lord of Creations
