They will make excuses to you when you have returned to them. Say, "Make no excuse - never will we believe you. Allāh has already informed us of your news [i.e., affair]. And Allāh will observe your deeds, and [so will] His Messenger; then you will be taken back to the Knower of the unseen and the witnessed,1 and He will inform you of what you used to do."

Tafsir
The hypocrites who stayed behind from striving in Allah’s path will present weak excuses to the Muslims when they return from their battle. Allah directs His Prophet and the believers to respond to them by saying: Do not make false excuses. We will never accept what you tell us because Allah has informed us about the excuses you make up. Allah and His Messenger will soon see whether you repent, in which case Allah will accept your repentance, or if you will persist in your hypocrisy. Then you will be returned to Allah, the One Who knows everything, and He will inform you about what you used to do and repay you for that. So rush towards repentance and good actions.
