What is the origin of the tashahhud in Salaah?

Was it part of a conversation between the Prophet (ﷺ) and Allah in the night journey?

The source to my best of knowledge is the hadith of Prophet Muhammad (ﷺ). Sheikh Albani talks about it in his book which talks about the Prophet's prayer. I don’t think that it was given to him on the night of M’iraj, but I might be wrong. [1]
