Does praying Fajr in congregation and then unintentionally committing a sin from which one repented mean that God is angry with them?

The Hadith referenced by the questioner is an authentic Hadith narrated by Muslim with the wording: "Whoever prays the Fajr prayer is under the protection of Allah. So, let not Allah demand anything from you regarding His protection, for whoever Allah demands something from regarding His protection, He will apprehend him and then cast him on his face into the Fire of Hell."
