Ramadan is the month of Allah in which Allah tests his creation by binding them from food and drinks. Fasting is obligatory on Muslims as it was on the religions before and Allah has obligated fasting for people to come close to Allah. Fasting is the sign which determine the relationship between men and Allah, which is based on total obedience and submission to him. Man willingly forgoes these needs in order to achieve his aim of winning the pleasure of Allah and earning His reward.
These are necessary elements in the training of the believers so that they are able to bear the pressures and hardships of the way they have chosen. It is the thorny way, full of obstacles. On both sides of it there are all sorts of pleasures and temptations that beckon the travelers, trying to force them off their course.
We know that fasting has numerous advantages and benefit for health, different scientist discover that fasting helps humans to become healthy and physically fit individuals. It goes without saying that Allah takes into consideration the physical constitution of man before He lays down his duties for him. We must not, however, relate our religious duties solely to what our human knowledge discovers. Our knowledge is, after all, limited and cannot comprehend fully the divine wisdom behind everything that relates to man and his education and training, let alone comprehend everything that relates to the universe.
According to the holy Quran in which Allah Almighty says (Believers, fasting is decreed for you as it was decreed for those before you, so that you may be God-fearing.) It means all those who believe in One God and Prophet Mohammad(pbuh) this is mandatory for them to fast in the holy month of Ramadan and apply prayer, ask forgiveness for their sins in the month and they will find Allah the most merciful will forgive them for their sin.
