question #2 Sahih al-Bukhari 724, Book 10, Hadith 118 : How did the practices in Medina change after the time of the Prophet Muhammad (ﷺ) according to the companions?

I arrived at Medina and was asked whether I found any change since the days of Allah’s Messenger (ﷺ). I
said, “I have not found any change except that you do not stand in alignment in your prayers.”
