Al-Qasas 28:46

Wama kunta bijanibi attooriith nadayna walakin rahmatanmin rabbika litunthira qawman ma atahum minnatheerin min qablika laAAallahum yatathakkaroon

And you were not at the side of the mount when We called [Moses] but [were sent] as a mercy from your Lord to warn a people to whom no warner had come before you that they might be reminded.

And you were not at the side of (the mount) Tūr when We called (Mūsā), but it (your prophet-hood through which you knew all this) is a mercy from your Lord, so that you warn a people to whom no warner has come before you, that they may receive the advice.
