ከተከበረው ካዕባ ማእዘን በመንካት ሰላምታ ማቅረብ የተደነገገው ለየትኞቹ ብቻ ነው?

The question asks for the viewpoint of Ahlus Sunnah wal Jama'ah concerning whether Jannah and Jahannam have been created and if they are eternal.

Ahlus Sunnah wal Jama'ah believes that Jannah and Jahannam have already been created and currently exist. They are not something that will be created in the future, nor have they ceased to exist. They are eternal.

• a) "ተፈጥረው የነበሩ ግን የጠፉና ወደፊት እጽ የሚፈጠሩ ናቸው" (They were created but ceased to exist, and will be created again in the future.) This contradicts the belief of Ahlus Sunnah wal Jama'ah.
• b) "ሾነትና እሰት በአሁኑ ገዚ የተፈጠረና የሌ" (Jannah and Jahannam are currently created and exist...) Although the option is cut off, the beginning aligns perfectly with the belief of Ahlus Sunnah wal Jama'ah that Jannah and Jahannam are already created and exist.

Based on the established Islamic belief of Ahlus Sunnah wal Jama'ah, the most accurate statement among the choices is option b.

The final answer is $\boxed{\text{b}}$
