We can make judgement only if we have experience.Existence proceed essence.Koran & phenomenology agree on this principle,which has major impact on our life in this world.
Koran show us this fact clearly in this verse:
(And follow not that of which thou(you) hast(have) no knowledge;Surely the hearing and sight and the heart,all of these will be asked about it.17:36).
This verse regard the perception(sensory+mental) as an act which must be based on knowledge(consciousness/awareness).Th sensory & mental are not separated in koran ,they are two moments of one act which named the categorial intution by Husserl .
Judgement become description of the lived experience & not consumed from others,prejudices. This is the core of Taqua(piety) in Koran. In phenomenology Taqua appeared as Epoche ,putting between brackets any prejudice ,presuppostion,which are responsible for the biases of our judgement.
The phenomenlogical experience is koranic & the koranic experience is phenomenological. Both of them put a premise to see the truth, which is the transformation of the ego(self) from emprical perspective(everyday attitude) to transcendental(reflective one.In the koran there is verse which describe this principle:
(For each (such person) there are (angels) in succession, before and behind him: They guard him by command of Allah. Verily never will Allah change the condition of a people until they change it themselves (with their own souls). But when (once) Allah willeth a people's punishment, there can be no turning it back, nor will they find, besides Him, any to protect)11-thunder .
The difference is in the way achieving this transformation.Koran seek practical,behaviouristic approach to change the self,through worshipping only one God,praying to only one God, fasting,haj,charity.All these strategeis are intended to purify the self from mundane ,worldly concerns.So the path of koran is reductive.Reduction of this cultural,social & psychological ego to the pure nature of the human being which is called in arabic called phutra(الفطره).These verses put emphasis on the inherent abilty of human to change their world, to confrount any suffering with peaceful mind.
