Dear Shahnawaz Saheb,
The Quran strongly negates the dogma of reincarnation which subscribes to a cyclical theory of life. The theory originated with Plato and was carried forward by Hindu philosophers. But the Quran corrects the fallacy by stressing that life is linear and ascending. Life in the Universe goes on with a linear ascending evolution with all creation adopting newer and higher forms.
11:56 “I have put my trust in God, my Lord and your Lord. There is not a creature in the Universe beyond His firm Control. Indeed, my Lord is on the STRAIGHT PATH.”
[God has designed the Universe so that all things go through evolution. It is an ascending, linear journey that makes progress possible. In the Cyclical hypothesis of the Greek philosophers, things will keep revolving in a circle like oxen endlessly going around a water well without covering any distance. Christian monasticism, Judaic mysticism, Hinduism, Buddhism, Sufism etc define the ultimate objective of humans as freeing themselves of the endless cycle of life. They call it 'salvation'. Therefore, salvation is a negative notion, whereas the Qur’an motivates us to attain eternal success. The dogma of Original Sin in Christianity also involves restoration to a sinless state, once again a negative connotation]
Ascent of the 'self', the Uphill Road, see 90:10-20.
90:10 And shown him the two highways? [Of virtue and vice]
90:11 But he hardly tries the uphill road, the Ascent.
90:12 Ah, what will convey to you what that Ascent is!
90:13 Freeing others from bondage, physical or mental, and from any social, economic or political oppression. [Freeing the neck includes all the above meanings and establishing the System wherein the only Master is God]
90:14 Feeding in times of hunger, famine, wars and natural disasters.
90:15 Taking special care of those who, despite being a part of the community, feel left out. [Za maqrabah = Near one = Relative = Part of the community]
90:16 Helping him who remains needy though he toils in the dust.
90:17 Being of those who have chosen to be graced with belief, and become living reminders of perseverance and living reminders of compassion.
90:18 Such are the companions of the right hand (immersed in bliss).
90:19 And those who deny Our messages, such are the companions of the left hand (immersed in despondence).
[Right Hand and Left Hand indicate the tropical significance of Mayimanah = Those on the side of righteousness. Mash’amah = Those on the side of evil]
90:20 With fire all around them.
[The Hellfire is such that its flames originate in the hearts and engulf the hearts. The fire of regret, anguish and despair. 104:6-8]
