('Amal). Work or action or practice. When faith and practice are combined with godfearingness then knowledge will be gained. The knowledge which brings man closer to Allah is not merely theoretical knowledge. Felicity is attained only when knowledge and practice (work, action) are combined. On the Journey of Return to the Source the traveller (salik) is required to put into practice every knowledge gained during his travelling. This will lead to further unveilings of knowledge, for in the words of the Holy Prophet Muhammad "He who acts upon what he knows, Allah will make him inherit that which he does not know".
