The evidences found in the Qur'an are like nutrition which everyone benefits from it.

Imam Ghazali said: 

"The evidences found in the Qur'an are like nutrition; everyone benefits from it. The evidences of the Mutakallimun are like medicine; some benefit from it whilst most are harmed by it. In fact, the evidences in the Quran are like water... it benefits the infant and also the strong man. All other evidences are like food; at times the strong may benefit from it and at other times they fall ill because of it."
