question #2 Sahih al-Bukhari 910, Book 11, Hadith 34 : How does maintaining silence during the Imam’s Khutba contribute to the forgiveness of sins?

Allah’s Messenger (ﷺ) (p.b.u.h) said, “Anyone who takes a bath on Friday and cleans himself as much as he
can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his
way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is
written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the
present and the last Friday will be forgiven.”
