These are the obstinate and stubborn unbelievers who stand exactly in opposite to the above mentioned VIRTUOUS PERSONS. Their qualifications in brief is said in the above verses. (NO. 6 & 7) The verse says: ``THEY BELIEVE NOT'' and it is alike to them whether you warn them of the chastisement of God, or do not warn them - they are so stubborn that they do not accept a truth even if they see it clearly! This is because, mentally, they are not ready for such acceptances.'' The next verse, (NO. 7) indicates the reasons for such an obstinacy and rejection of truth by saying: ``Allah Has set a seal upon their hearts, and upon their ears, and there is a covering upon their eyes, and there is a great chastisement for them.'' A man who has not reached to such a condition, may still be liable to guidance; but when he lost his power of comprehension and distinction, there remains no way for his salvation. Such a man, for losing all the means and instruments of understandings and grasping the fact; will meet a natural torment, or heavenly chastisment.
