question #3 Sahih al-Bukhari 862, Book 10, Hadith 253 : What does this narration suggest about the Prophet’s awareness of his community’s activities and needs?

Once Allah’s Messenger (ﷺ) delayed the `Isha’ prayer till `Umar informed him that the women and children
had slept. Then Allah’s Messenger (ﷺ) came out and said: “None from amongst the dwellers of earth have
prayed this prayer except you.” In those days none but the people of Medina prayed.
