Here are some quotes of Islamic scholars on the benefits of reciting and memorizing Quran.
The thought of losing one’s mind due to old-age, illness or an accident is most certainly a worrying one to say the least.
The gift of sanity, especially for a Muslim who consciously seeks to invest in every single second in preparation for the Hereafter, is a particularly precious one.
With that said,
‘Abdul Malik Ibn ‘Umair said,
“It used to be said, ‘The people who are protected most in respect to their minds are the reciters of the Qur’an’”
In another narration,
“The purest of people in terms of their minds are the reciters of the Qur’an.”
Imam Al-Qurtubi said,
“Whoever recites the Qur’an (i.e. frequently) will enjoy soundness in his mind, even if he hits the age of 100.”
Imaam Ibn Taymiyya said,
“I have never come across anything which nourishes the mind and soul, preserves the body and guarantees one’s happiness like that of perpetual looking into the Qur’an.”
