question #1 Sahih al-Bukhari 1070, Book 17, Hadith 4 : What is the significance of prostration during the recitation of certain verses in the Quran?

The Prophet (ﷺ) recited Surat-an-Najm (53) and prostrated while reciting it and all the people prostrated and a man amongst the people took a handful of stones or earth and raised it to his face and said, “This is sufficient for me. Later on I saw him killed as a non-believer.”
