[Mention, O Muḥammad], the Day We will call forth every people with their record [of deeds].1 Then whoever is given his record in his right hand - those will read their records, and injustice will not be done to them, [even] as much as a thread [inside the date seed].
Translation: Saheeh International (English)
1 Other meanings are "with their leader" or "with that which they had followed."

Tafsir
And remember, O Messenger, when every group will be called out by their leader whom they used to follow in life. So whoever is given his book of deeds in his right hand - they will read their books happily. And nothing will be decreased from their reward, be it as small as the thread on a date seed.
