quran:88:6

For them there will be no food except from a poisonous, thorny plant  

They will have no food except cactus (darī‘) — a type of thorn plant which no animal grazes on because of its vileness —
القرآن:٨٨:٦

لَيْسَ لَهُمْ طَعَامٌ إِلَّا مِنْ ضَرِيعٍ  

{ليس لهم طعام إلا من ضريع} هو نوع من الشوك لا ترعاه دابة لخبثه.
