Translation:

46. Wealth and sons are allurements of the life of this world: but the things that endure Good Deeds are best in the sight of thy Lord as rewards and best as (the foundation for) hopes.

Notes (Tafseer)

2387. Other things are fleeting: but Good Deeds have a lasting value in the sight of Allah. They are best as (or for) rewards in two ways: (1) they flow from us by the Grace of Allah, and are themselves rewards for our Faith: (2) they become the foundation of our hopes for the highest rewards in the Hereafter.
