Translation:

12. Verily We shall give life to the dead and We record that which they sent before and that which they leave behind and of all things have We taken account in a clear Book (of evidence).

Notes (Tafseer)

3954. All this is possible, because there is the assurance of a Hereafter, in which Allah will be all-in-all, and evil will no longer bestride the world, as the term of its respite will have expired.

3955. Our deeds, good and bad, go to Allah before us. They will of course be brought to our account; but our account will also be swelled by the example we left behind us and the consequences of our deeds, that will come into play or continue to operate after our earthly life has ceased. Our moral and spiritual responsibility is therefore much wider than as affects our own person.

3956. Cf. ii. 124 and n. 124. All our account will be exactly preserved as in a book of record.
