I was wondering what the language of Adam was? (What was the language that he used to speak with?)
I searched to some extent (in the internet), I found two related Farsi (Persian) sites which I deem them as valid sites, but there seems to be several probable issues about the accurate answer, including:
1: It is remarked that Allah taught Adam all languages.
2: It is said that old Syriac language, namely the mother of Sami and Arabic was his language.
3: It can be feasible that he was talking in Arabic, since the language of Paradise seems to be Arabic.
4: Adam was talked in Arabic, but his language changed into Syriac after committing the sin and coming to the earth.
I wonder which answer/theory can be more accurate?
