Is the recitation of a Surah after Al-Fatiha prescribed in the funeral prayer, and what is the evidence for that from Sahih Al-Bukhari?

The four schools of thought (madhahib) agree that no surah should be recited after Al-Fatiha in the funeral prayer (Salat al-Janazah). However, they differed on the recitation of Al-Fatiha itself: the Malikis and those who agreed with them do not consider it prescribed, while the Hanbalis and Shafi'is consider it a pillar (rukn). Sheikh al-Islam Ibn Taymiyyah, on the other hand, considered it only a recommended act (mustahabb). A narration from Ibn Abbas indicates the recitation of Al-Fatiha and a surah in the funeral prayer, but the mention of the surah in this narration is a point of contention among scholars.
