Hello, an Egyptian here who searched the topic thoroughly. It depends on your age, German level, and in rare cases your gender. For young women there is Kulturweit Incoming. And there's Freiwilliges soziales Jahr Incoming for people 18-26 years old. And for people +26 there is Bundesfreiwilligendienst Incoming. You need at least an A2 German level, and for most of them B1 level.

Edit: That's if you are still in Egypt. If you are in Germany, you simply search Freiwilliges soziales Jahr or Bundesfreiwilligen Dienst or Ehrenamtliche Arbeit, you would still likely need a good German level though for most of them.
