Yusuf Ali
The Unbelievers say, "Never to us will come the Hour": Say, "Nay! but most surely, by my Lord, it will come upon you;- by Him Who knows the unseen,- from Whom is not hidden the least little atom in the heavens or on earth: Nor is there anything less than that, or greater, but is in the Record Perspicuous:

Sahih International
But those who disbelieve say, "The Hour will not come to us." Say, "Yes, by my Lord, it will surely come to you. [Allah is] the Knower of the unseen." Not absent from Him is an atom's weight within the heavens or within the earth or [what is] smaller than that or greater, except that it is in a clear register -

Shakir
And those who disbelieve say: The hour shall not come upon us. Say: Yea! by my Lord, the Knower of the unseen, it shall certainly come upon you; not the weight of an atom becomes absent from Him, in the heavens or in the earth, and neither less than that nor greater, but (all) is in a clear book

Pickthall
Those who disbelieve say: The Hour will never come unto us. Say: Nay, by my Lord, but it is coming unto you surely. (He is) the Knower of the Unseen. Not an atom´s weight, or less than that or greater, escapeth Him in the heavens or in the earth, but it is in a clear Record,

اور کافر کہتے ہیں کہ (قیامت کی) گھڑی ہم پر نہیں آئے گی۔ کہہ دو کیوں نہیں (آئے گی) میرے پروردگار کی قسم وہ تم پر ضرور آکر رہے گی (وہ پروردگار) غیب کا جاننے والا (ہے) ذرہ بھر چیز بھی اس سے پوشیدہ نہیں (نہ) آسمانوں میں اور نہ زمین میں اور کوئی چیز ذرے سے چھوٹی یا بڑی ایسی نہیں مگر کتاب روشن میں (لکھی ہوئی) ہے
