We often use the term "Hafiz e Quran" for the people who have memorized it. But as far I know Hafiz is one of the attribute of Allah. So it seems like shirk to use this term for a person who memorizes it. Can anyone please let me know -

Is it a jaiz term to use for people who memorizes Quran?

which term did come in Quran and Hadith for the people who memorized Quran?

From when this term "Hafiz e Quran" is being used for the people who memorize it?

Please give answer with the reference from Quran and Hadith with the reference number so that I can cross check.
