What language did God Almighty speak with Adam and Moses (peace be upon them)?

The maximum that was mentioned about Allah’s speech to Adam (peace be upon him) is His saying: ﴿وَقُلْنَا يَا آدَمُ اسْكُنْ أَنْتَ وَزَوْجُكَ الْجَنَّةَ﴾ [And We said, "O Adam, dwell, you and your wife, in Paradise"]. As for the language in which He spoke to him, there is no evidence for it, and it suffices us to remain silent about what the Shari'a remained silent about. As for Moses (peace be upon him), his tongue was Hebrew, and Allah revealed to him in it. Ibn Taymiyyah said: "Allah revealed to Moses in Hebrew, and to Muhammad (peace and blessings be upon him) in Arabic."
