Unfortunately those who have religious ardor are two groups: One group follow the way of Rabi' and think of Islam only as a creed for prayers, hymns and pilgrimage and refer to certain standard books of theology to guide them. They have nothing to do with the world or social regulations or Islamic principles and education. The reaction to the slowness of this group is the appearance of a second group who go too fast and move on the path of excess.
They pay all their attention to social matters, which in itself is a worthy attitude, but ignore acts of worship. I have met people who can well afford to go on a pilgrimage to Mecca, an injunction which is regarded as an important matter in Islam. They ignore prayers, and put aside the matter of imitating a religious leader. They believe that problems related to acts of worship should be solved by oneself, without the need of the guidance of others.
Thus everyone is assumed to be a religious expert or a jurisprudent. One is one's own physician and has no need of consulting a doctor or a specialist. There are some who are slack in fasting and its conditions in the case of permanent residence or on a journey and do not believe in making amends for failure to perform acts of worship in their proper time and place. Both groups consider themselves Muslims but they are not wholly so.
Islam does not agree with the phrase, "To believe in some things and disbelieve in other things."79It cannot agree with the acceptance of worship coupled with the rejection of its moral and social questions, or vice versa. You notice that whenever the Quran says, "Perform your ritual prayer," it is followed by, "Pay your alms." The first injunction concerns the relation between a creature and God and the second one shows the relation between one creature and others.
Thus a true Muslim has a dual responsibility towards God and towards human beings and to their society in a permanent way. No Islamic society can be built without worship and invocation of God and prayer and fasting. In the same way, no pious society can exist without directing to goodness and forbidding evils and without kindly relations between individuals, even though a person may be a pious individual.
We see Ali, peace be upon him, as the most exalted, pious man, so much so that his worship was proverbial, a worship full of terror and love and tears.
