سورة القمر

Imam Sadiq (peace be upon him): I found names for the people of qadar (the Qadariyya) in the Book of Allah [and one of them is]: إِنَّ الْمُجْرِمِینَ فِی ضَلالٍ وَ سُعُرٍ یَوْمَ یُسْحَبُونَ فِی النَّارِ عَلی وُجُوهِهِمْ ذُوقُوا مَسَّ سَقَرَ إِنَّا کُلَّ شَیْءٍ خَلَقْناهُ بِقَدَرٍ [Surely the guilty are in error and distress. On the day when they are dragged upon their faces into the Fire: taste the touch of Saqar. Surely We have created everything according to a measure] — so they are the guilty ones.

Imam Sadiq (peace be upon him): Allah did not send down these verses except concerning the Qadariyya: إِنَّ الْمُجْرِمِینَ فِی ضَلالٍ وَ سُعُرٍ یَوْمَ یُسْحَبُونَ فِی النَّارِ عَلی وُجُوهِهِمْ ذُوقُوا مَسَّ سَقَرَ إِنَّا کُلَّ شَیْءٍ خَلَقْناهُ بِقَدَرٍ [Surely the guilty are in error and distress. On the day when they are dragged upon their faces into the Fire: taste the touch of Saqar. Surely We have created everything according to a measure].

Ali ibn Ibrahim (may Allah have mercy on him): The verse إِنَّ الْمُجْرِمِینَ فِی ضَلالٍ وَ سُعُرٍ [Surely the guilty are in error and distress] means they are in torment, and Su'ur is a vast wilderness in hell.
