question #1 Sahih Muslim 454a, Book 4, Hadith 182 : What does this narration indicate about the length of the Prophet’s prayer during the noon prayer?

The noon prayer would start and one would go to al-Baqi’ and after having relieved himself he would perform ablution and then come, while the Messenger of Allah (ﷺ) would be in the first rak’ah, because he would prolong it so much.
