Sahih Bukhari 7517: Meraj And Issues With The Hadith Of Shareek Bin Abdullah
This whole hadith is referring to only one incident where Prophet Muhammad (sws) was ascended to heavens in that dream and shown various signs and experiences. Three angels which came that night were the same three angels which came to him in a dream even before his prophethood and at that time and they did not do anything, just identified him and that’s it. Then after prophethood, the same three angels came to the Prophet (SWS) and put him beside ZamZam and then the Hadith continues. It is this commonality of these three angels due to which linkage was established with one dream before prophethood and then a dream after prophethood.
