At-Tawbah · 9:105

105. Say, O Messenger, to those who had stayed behind from striving in Allah’s path and who have repented from their sin: : Make up for the harm caused by what you missed and be sincere in your actions to Allah. Do what pleases Him, because Allah, His Messenger and the believers will soon see your actions. Then you will be returned, on the Day of Judgement, to your Lord, the One Who knows everything. He knows what you hide and what you make public and He will inform you about what you used to do in the world and repay you for that.
