Having refuted the claim of the Jews as baseless, the Holy Qur'an lays down the divine law in this regard. Those who commit evil deeds knowingly and deliberately so that evil takes hold of them completely, leaving no trace of goodness - such men shall go to the Hell, and live there forever, without any intermission or release. But those who believe in Allah and the Holy Prophet ﷺ - whose Shari` ah has now abrogated all the earlier Shari'ahs and who do good deeds in conformity with the Islamic Shari'ah, - it is these men who shall go to Paradise, and will live there forever.
Let us explain how evil can take hold of a man so completely that no trace of goodness is left. This kind of thing happens only to infidels (Kafirs کفار), and not to Muslims, even when they are sinners. For, no good deed on the part of an infidel is acceptable to Allah on account of his infidelity; even the good deeds he has done before his apostasy and infidelity are lost, and rendered null and void. That is why on the Day of Judgment, infidels will have to show nothing but evil, in punishment of which they shall live in Hell for ever. On the contrary, men of faith will, to begin with, have the greatest and highest good deed to their credit - namely, faith ('Iman ایمان) itself. Then, their secondary good deeds too are recorded in their account. So, they cannot be devoid of all goodness, and evil cannot be said to have taken hold of them completely.
In short, the infidel, according to this divine law, must always live in Hell. Since Sayyidna Musa (علیہ السلام) (Moses) was not the last prophet, but was followed by two other prophets, Sayyidna ` Isa (علیہ السلام) (Jesus) and Sayyidna Muhammad ﷺ ، the Jews turned into infidels by denying these two prophets. So, in accordance with this law, they too will be assigned to Hell for ever like other infidels, and their claim that they would be released from Hell after few days can now be seen to be totally false and baseless.
