Fasting in the month of Ramadan is one of the five pillars upon which the structure of Islam is built. The other four are the declaration of one’s belief in God’s oneness and in the message of Muhammad (peace be upon him), regular attendance to prayer, payment of zakah (i.e. obligatory charity), and the pilgrimage.
If we examine these five pillars, taking into account the fact that Islam aims at improving the quality of human life at both the individual and social levels, we find that the first of these five pillars is concerned with beliefs that influence man’s conduct. The second, i.e. prayer, provides a constant reminder of man’s bond with God. Zakah, the third pillar, is a social obligation that reduces the gap between the rich and the poor, while the fifth, i.e. the pilgrimage, has a universal aspect that unites the Muslim community throughout the world.
Fasting in Ramadan, which is the fourth of these pillars, has a particularly high importance, derived from its very personal nature as an act of worship. Although in a Muslim country, it is extremely difficult for anyone to defy public feelings by showing that one is not fasting, there is nothing to stop anyone from privately violating God’s commandment of fasting if one chooses to do so. This means that although fasting is obligatory, its observance is purely voluntary. The fact is that fasting cannot be used by a hypocrite in order to persuade others of one’s devotion to God. If a person claims to be a Muslim, he is expected to fast in Ramadan. On the other hand, a person fasting voluntarily at any other time should not tell others of the fact. If he does, he detracts from his reward for his voluntary worship. In fact, people will find his declaration to be fasting very strange and will feel that there is something wrong with it.
This explains why the reward God gives for proper fasting is so generous. In a sacred, or Qudsi hadith, the Prophet quotes God as saying: “All actions done by a human being are his own except fasting, which belongs to Me and I reward it accordingly.” This is a mark of special generosity since God gives for every good action a reward equivalent to at least ten times its value. Sometimes He multiplies this reward to seven hundred times the value of the action concerned, and even more. We are also told by the Prophet that the reward for proper fasting is admittance into heaven.
