Allah is the sole source of the right knowledge, besides the adjudicator to define moral and immoral and that believer would require to be oriented to perfectly receive his divine will and directives, in order to inculcate these attributes. Indeed, memorising 90 names of Allah is not enough, albeit it requires knowledge of these attributes without a single contradiction/abrogation/interpretation with vested interest to enable him to understood the nature or ‘zaat’ of the Almighty. Allah certainly has built the rule of law, thus the holy Quran always edicts for ‘evenness’ among all his beloved creations. The God is Al-Adl (just) not for Muslims only but for everyone in the Universe, monotheist/polytheist/Atheist and no one to be at advantage or disadvantage.
Allah’s vanity showers without any differentiation of superior or inferior. Allah is the epitome of morality or what maximises good. Hell is also a part of mercy to check the world turning into oppressive place with injustice and misery, to live. It explicitly clarifies that these are the acts of human beings including peace, tolerance and love, which entitles him for ‘Heaven’ or otherwise ‘Hell’. The creation of ‘Hell’ as well as ‘Heaven’ was aimed to direct the people to work for peace, harmony and tolerance in order to be claimant of the later.
If the warning of Punishment in Hell wasn’t a Mercy, but a strict warning against deeds, Allah refrains:
‘Was Allah Unjust in Creating Adam and Favouring His Progeny Over All His Creation?’
‘When the sky is rent asunder, and it becomes red like ointment’ (55:37)
‘Then which of the favours of your Lord will ye deny?’ (55:38)
‘On that Day no question will be asked of man or Jinn as to his sin.’ (55:39)
‘Then which of the favours of your Lord will ye deny?’ (55:40)
Thus, everyone who follows Almighty’s attributes is entitled of ‘Jannat’ and those who indulge in violence, hatred and disharmony to ‘Hell’ hereinafter.
