to accept a non believer's (good) deeds and make him enter paradise. But the Just Lord gives them the reward for it in this very world, like ease during death, healthiness, wealth etc. as discussed earlier. But it is possible that there
may be leniency in their punishment, as in the case of Hatim Tai or Nawshirwane Adil who were generous, they shall be made to enter hell, but the fire will not harm them.
As said in the Qur' an: "Nor (for) those who die while they are unbelievers". (surah-an-Nisa : 18)
In another place it is stated : "And (as to) those who reject our communications and the meeting of the Hereafter, their deeds are null. Shall they be rewarded except for what they have done". (surah- al-A'araf :147).
Many verses (ayah) of the Qur'an prove that disbelief (kufr) and polytheism (shirk) wastes away all good deeds. Then there are also such sins that obliterate good deeds
and stop them from being accepted. The Holy prophet (S.A.W.S.) has said regarding a disobedient child: "O the one shunned away by his parents do whatever you like, for none of your (good) deeds will be accepted". If a person has upon him the curses and woes of his mother, he will be thrown into hell even if his good deeds are equal to the size of a mountain. Also is the case with slander and jealousy. Ma'soom (A.S.) says, "Jealousy consumes faith (Eeman) just as fire consumes wood". (ma'ad). Shaikh Kulaini
