This was said by Ibn `Abbas, Qatadah and Ibn Zayd. It has been called this because it will overwhelm the people and overcome them. Allah then says,

﴿وُجُوهٌ يَوْمَئِذٍ خَـشِعَةٌ ﴾

(Some faces that Day will be Khashi`ah.) meaning, humiliated. This was said by Qatadah. Ibn `Abbas said, "They will be humble but this action will be of no benefit to them.'' Then Allah says,

﴿عَامِلَةٌ نَّاصِبَةٌ ﴾

(Laboring, weary.) meaning, they did many deeds and became weary in their performance, yet they will be cast into a blazing Fire on the Day of Judgement. Al-Hafiz Abu Bakr Al-Burqani narrated from Abu `Imran Al-Jawni that he said, " `Umar bin Al-Khattab passed by the monastery of a monk and he said: `O monk!' Then the monk came out, and `Umar looked at him and began to weep. Then it was said to him: `O Commander of the faithful! Why are you weeping' He replied: `I remembered the statement of Allah, the Mighty and Majestic, in His Book,

﴿عَامِلَةٌ نَّاصِبَةٌ - تَصْلَى نَاراً حَامِيَةً ﴾

(Laboring, weary. They will enter into Fire, Hamiyah.) So that is what has made me cry. ''' Al-Bukhari recorded that Ibn `Abbas said,

﴿عَامِلَةٌ نَّاصِبَةٌ ﴾

(Laboring, weary.) "The Christians.'' It is narrated that `Ikrimah and As-Suddi both said, "Laboring in the worldly life with disobedience, and weariness in the Fire from torment and perdition.'' Ibn `Abbas, Al-Hasan, and Qatadah all said,

﴿تَصْلَى نَاراً حَامِيَةً ﴾

(They will enter into Fire, Hamiyah) meaning, hot with intense heat.

﴿تُسْقَى مِنْ عَيْنٍ ءَانِيَةٍ ﴾

(They will be given to drink from a boiling (Aniyah) spring.) meaning, its heat has reached its maximum limit and boiling point. This was said by Ibn `Abbas, Mujahid, Al-Hasan and As-Suddi. Concerning Allah's statement,

﴿لَّيْسَ لَهُمْ طَعَامٌ إِلاَّ مِن ضَرِيعٍ ﴾

(No food will there be for them but from Dari`,) `Ali bin Abi Talhah reported from Ibn `Abbas that he said, "A tree from the Hellfire.'' Ibn `Abbas, Mujahid, `Ikrimah, Abu Al-Jawza' and Qatadah, all said, "It is Ash-Shibriq (a type of plant).'' Qatadah said, "The Quraysh called it Ash-Shabraq in the spring and Ad-Dari` in the summer.'' `Ikrimah said, "It is a thorny tree which reaches down to the ground.'' Al-Bukhari related that Mujahid said, "Ad-Dari` is a plant that is called Ash-Shibriq. The people of the Hijaz call it Ad-Dari` when it dries, and it is poisonous.'' Ma`mar narrated that Qatadah said,

﴿لَّيْسَ لَهُمْ طَعَامٌ إِلاَّ مِن ضَرِيعٍ ﴾

(No food will there be for them but from Dari`,) "This is Ash-Shibriq. When it dries it is called Ad-Dari`.'' Sa`id narrated from Qatadah that he said,

﴿لَّيْسَ لَهُمْ طَعَامٌ إِلاَّ مِن ضَرِيعٍ ﴾

(No food will there be for them but Dari`,) "This is of the worst, most disgusting and loathsome of foods.'' Concerning Allah's statement,

﴿لاَّ يُسْمِنُ وَلاَ يُغْنِى مِن جُوعٍ ﴾

(Which will neither nourish nor avail against hunger.) This means that the intent in eating it will not be achieved, and nothing harmful will be repelled by it.

﴿وُجُوهٌ يَوْمَئِذٍ نَّاعِمَةٌ - لِّسَعْيِهَا رَاضِيَةٌ فِى جَنَّةٍ عَالِيَةٍ لاَّ تَسْمَعُ فِيهَا لَـغِيَةً فِيهَا عَيْنٌ جَارِيَةٌ فِيهَا سُرُرٌ مَّرْفُوعَةٌ وَأَكْوَابٌ مَّوْضُوعَةٌ وَنَمَارِقُ مَصْفُوفَةٌ وَزَرَابِيُّ مَبْثُوثَةٌ ﴾

(8. Faces that Day will be joyful,) (9. Glad with their endeavor.) (10. In a lofty Paradise.) (11. Where they shall neither hear harmful speech nor falsehood.) (12. Therein will be a running spring.) (13. Therein will be thrones raised high.) (14. And cups set at hand.) (15. And Namariq, set in rows.) (16. And Zarabi, spread out (Mabthuthah).)
