question #3 Sahih al-Bukhari 4807, Book 65, Hadith 329 : How does the example of Prophet David influence the practices of Prophet Muhammad (ﷺ)?

I asked Mujahid regarding the prostration in Surat Sa`d. He said, “I asked Ibn `Abbas, ‘What evidence
makes you prostrate?’ He said, “Don’t you recite:–‘And among his progeny, David and
Solomon..(6.84). Those are they whom Allah had guided. So follow their guidance.’ (6.90) So David
was the one of those prophets whom Prophet (Muhammad) was ordered to follow. David prostrated,
so Allah’s Messenger (ﷺ) (Muhammad) performed this prostration too.’
