Quran 67:7 · Al-Mulk

At various places in the Quran, the picture of hell has been drawn. Though this hell is not observable today by man, it can be seen indirectly and imagined through the meaningfulness of the universe. The fact is that if there were to be no reckoning of the evil people brought to account in the Hereafter, the entire meaningfulness of the universe would become inexplicable. The punishment of the Hereafter not being visible in the present world is precisely in accordance with God’s plan. It is the intention of God to select such persons as are convinced of His greatness and who obey Him without actually having seen Him. And the assessment of such people cannot be properly made unless the fate awaiting everybody in the Hereafter is kept out of their sight, so that whatever a man does here, he does out of free will and not under any compulsion.
