My interest in the subject of the personality of the Muslim, as Islam conceived it, goes back more than a decade. I noticed, during these years, that many Muslims often preoccupied with certain practices while neglecting others.

You may find, for example, that a Muslim insists on being present in the first row in all prayers. Yet he pays no attention to the bad smell emanating from his mouth or his clothes. He obeys, of course, and fears Allah, but he neglects the bonds of kinship. Or he spends a lot of time in worship and studies, neglecting to bring up his children. He doesn't know what they read or who their friends are. He can take care of his children, but he mistreats his parents. He can take care of his parents, but at the expense of his wife. He can treat his wife and children with respect, while disturbing his neighbors. Or he is a man of religion, pious but not paying attention to Islamic principles such as greeting others, consuming food and drink or having intercourse with others.
