Yusuf Ali
In whatever business thou mayest be, and whatever portion thou mayest be reciting from the Qur´an,- and whatever deed ye (mankind) may be doing,- We are witnesses thereof when ye are deeply engrossed therein. Nor is hidden from thy Lord (so much as) the weight of an atom on the earth or in heaven. And not the least and not the greatest of these things but are recorded in a clear record.

Sahih International
And, [O Muhammad], you are not [engaged] in any matter or recite any of the Qur'an and you [people] do not do any deed except that We are witness over you when you are involved in it. And not absent from your Lord is any [part] of an atom's weight within the earth or within the heaven or [anything] smaller than that or greater but that it is in a clear register.

Shakir
And you are not (engaged) in any affair, nor do you recite concerning it any portion of the Quran, nor do you do any work but We are witnesses over you when you enter into it, and there does not lie concealed from your Lord the weight of an atom in the earth or in the heaven, nor any thing less than that nor greater, but it is in a clear book.

Pickthall
And thou (Muhammad) art not occupied with any business and thou recitest not a Lecture from this (Scripture), and ye (mankind) perform no act, but We are Witness of you when ye are engaged therein. And not an atom´s weight in the earth or in the sky escapeth your Lord, nor what is less than that or greater than that, but it is (written) in a clear Book.

محمد جالندھری
اور تم جس حال میں ہوتے ہو یا قرآن میں کچھ پڑھتے ہو یا تم لوگ کوئی (اور) کام کرتے ہو جب اس میں مصروف ہوتے ہو ہم تمہارے سامنے ہوتے ہیں اور تمہارے پروردگار سے ذرہ برابر بھی کوئی چیز پوشیدہ نہیں ہے نہ زمین میں نہ آسمان میں اور نہ کوئی چیز اس سے چھوٹی ہے یا بڑی مگر کتاب روشن میں (لکھی ہوئی) ہے
