الَّذِينَ كَفَرُواْ وَصَدُّواْ عَن سَبِيلِ اللّهِ زِدْنَاهُمْ عَذَابًافَوْقَ الْعَذَابِ بِمَا كَانُواْ يُفْسِدُونَThose who disbelieved and tried to obstruct the path of Allah, for them We will add torment,meaning one punishment for their disbelief and another punishment for turning others away from following the truth, as Allah says:وَهُمْ يَنْهَوْنَ عَنْهُ وَيَنْأَوْنَ عَنْهُAnd they prevent others from him and they themselves keep away from him. (6:26)meaning they forbade others to follow him and they themselves shunned him, but:وَإِن يُهْلِكُونَ إِلاَّ أَنفُسَهُمْ وَمَا يَشْعُرُونَthey destroyed only themselves, while they do not realize it. This is evidence that there will be varying levels of punishment for the disbelievers, just as there will be varying degrees of Paradise for the believers, as Allah says:قَالَ لِكُلٍّ ضِعْفٌ وَلَـكِن لاَّ تَعْلَمُونَFor each one there is double (torment), but you know not. (7:38)
