question #3 Sahih Muslim 973b, Book 11, Hadith 129 : What can be learned about the practices of the Prophet Muhammad (ﷺ) regarding funeral prayers from this narration?

How hastily the people criticise that about which they know little. They criticise us for carrying the bier in the mosque. The Messenger of Allah (ﷺ) offered not the funeral prayer of Suhail b. Baida’ but in the innermost part of the mosque.
