The inner spirit of the outer manifestation of fasting in the month of Ramzan is to endure. A man who keeps fast will soon learn to tolerate even unpleasant situations. He will ignore what may be objectionable and concentrate on positive aspects of the matter.
Those who adhere to these five pillars of Islam only to the extent of their manifestations, will find that their lives are devoid of the spirit of these pillars.
For example they will repeat the words accepting the oneness of God and the prophethood of Muhammad, but beyond these words when they are confronted with truth, they will not accept it, because they have not understood the spirit of what they repeat. They will go through the ritual of prayer (Namaz) but once outside the mosque they will not be able to display the humility in their interaction with others. The reason for this is that they have not imbibed the spirit of Namaz.
Likewise those who take out a fixed amount as alms (Zakat), will not show any compassion while dealing with others. Because the spirit of Zakat is missing. They will go for Hajj, perform the rituals and come back. But they will not be ready to ignore the complaints of the others and forge a unity because the true spirit of Hajj has not touched them. During the month of Ramzan, they will keep the ritual fast. But when they are required to show patience, they will be found lacking. They will be easily provoked. The reason for this is that they have not understood the spirit behind the fasting.
Anyone who has adhered to the five pillars of Islam is a faithful and a Muslim. He has made himself entitled to God’s bounty, in this world as well as in the world hereafter. But the five pillars of Islam have to be accepted in their manifestations and spirits. The rewards, which have been promised, are for their complete and not partial adherence.
