 مَّثَلُ الَّذِينَ كَفَرُواْ بِرَبِّهِمْ أَعْمَالُهُمْ كَرَمَادٍ اشْتَدَّتْ بِهِ الرِّيحُ فِي يَوْمٍ عَاصِفٍ لاَّ يَقْدِرُونَ مِمَّا كَسَبُواْ عَلَى شَيْءٍ ذَلِكَ هُوَ الضَّلاَلُ الْبَعِيدُ 14:18

(Fathe Muhammad Jalandari)
جن لوگوں نے اپنے پروردگار سے کفر کيا ان کے اعمال کي مثال راکھ کي سي ہے کہ آندھي کے دن اس پر زور کي ہوا چلے (اور) اسے اڑا لے جائے (اس طرح) جو کام وہ کرتے رہے ان پر ان کو کچھ دسترس نہ ہوگي. يہي تو پرلے سرے کي گمراہي ہے 14:18

(Muhammad Assad)
 14:18 [This, then, is] the parable of those who are bent on denying their Sustainer: all their works are as ashes which the wind blows about fiercely on a stormy day: [in the life to come,] they cannot achieve any benefit whatever from all [the good] that they may have wrought: for this [denial of God] is indeed the farthest one can go astray. 14:18

(Yousaf Ali)
 14:18 The parable of those who reject their Lord is that their works are as ashes, on which the wind blows furiously on a tempestuous day: No power have they over aught that they have earned: that is the straying far, far (from the goal).14:18
