Аль-Гашия 88:6

لَّيْسَ لَهُمْ طَعَامٌ إِلَّا مِن ضَرِيعٍ (There will be no food for them except from a thorny plant...88:6) The only food available for the inmates of Hell would be dari`. In the world, this is a kind of thorny grass that spreads on the ground. No animal goes near it. It is foul-smelling, poisonous and thorny. [ As interpreted by ` Ikrimah, Mujahid, and quoted by Qurtubi ].

How will Grass or Tree Survive in Hell

One may ask the question that the grass or trees are among things

that burn in fire. How will they survive in Hellfire? The answer is that the Supreme Creator Who cherished and sustained them in this world with water and air, has the power and ability to make the fire itself the nutrient of these trees, so that they may flourish.

Another question may be raised here. The Qur'an mentions several things as the food of the inmates of Hell. Here it refers to their food as dart`. On another occasion, it refers to zaqqum, and on a third occasion it refers to ghislin. This verse restricts their food to dari', thus: 'There will be no food for them except from a thorny plant...88:6)

The answer is that the restriction in this verse is in contrast to a palatable food that may be fit for [ human ] consumption. Dari` is cited here as an example. The verse means that the inmates of Hell will not get any palatable food. They will get worst, most disgusting and loathsome food like Dari`. Thus the purpose of mentioning Dari` is not restriction. In fact, Dari` includes zaqqum and ghislin. Qurtubi says that it is possible there will be different levels in Hell, and on different levels there will be different kinds of food. On one level, there will be dart` and on another level, ghislin, and so on.
