Philosophers have conducted a wise analysis on this concept and have come to the conclusion that the common aspect among all these goods consists of the perfection of the being and the common aspect among all the evils consists of the imperfection of the being. For instance, when we compare an ignorant man with a learned man, we observe that the learned man has a perfection which the ignorant man lacks. So, the being of the learned man is more perfect than the being of the ignorant man, and/or since a sick man does not have the power to defend against diseases and cannot confront aggressive microbes and loses his body's balance, his being is imperfect compared to a healthy person. A brave man, in various phases, can achieve his goals, but a timid and cowardice cannot.
Basi pale tunaposema kua Uislamu umeleta mapinduzi katika fikra za wanaadamu, tunakusudia kua Uislamu ulipokuja uliyakuta baadhi ya mambo yaliyokua hayapewi thamani ndani ya jamii ukayapa thamani, na kuna mengine yaliyoonekana kua ni yenye thamani ukayashusha thamani, moja kati ya yale yaliyopewa thamani na Uislamu ni Ucha Mungu, Uislamu ulipokuja ulilitilia mkazo suala hili na kulipa thamani ya hali ya juu kabisa, na Mwenye Enzi Mungu akaahidi zawadi yenye thamani kubwa kwa kila atakayelitilia mkazo na kushikamana na suala hilo, na moja ya yale yaliyoshushwa thamani na Uislamu ni ukabila, suala ukabila lilikua ni lenye kupewa kipau mbele sana kabla ya kuja kwa Uislamu, lakini Uislamu ulipokuja ulilishusha daraja suala hili hadi thamani ya suala hili ikagonga zero katika kushuka kwake thamani.
