Quran and mental health:

 «Those who believe (in the Oneness of Allah - Islamic Monotheism), and whose hearts find rest in the remembrance of Allah, Verily, in the remembrance of Allah do hearts find rest.»Ar-Raad:28

 ------

Al-Tabari says in Tafsir:"by remembering Allah, the hearts of believers will be pacified and quietened". In the hustle and bustle of the world, and between the hardships of the days, the Qur'an calms the pains of the soul, hearts and calms the fear of the frightened.. Allah does not leave a gap for his servants to get lost, but covers them with the end of his mercy, and he inspired his words to calm souls.

« And We send down from the Quran that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss.»Al-Isra 82

If a troubled person hears Quran, Quran dwells his terribles, and if he seeks to keep Quran in heart, The Quran will save him and take care of him, and if he takes verses asa refuge, he will be safe. Healing with the Qur'an is not only to cure ignorance, but to increase insight and to know the extent of Allah's mercy and Grace, reassuring his heart.

For example, in the story of the Prophet Noah, Allah reminds the Prophet Muhammad that he was not the only one who was rejected, Noah also suffered hundreds of years, and few believed with him. From the story of Adam (peace be upon him), we see that human error is possible, and that the best of mankind is wrong and ask for forgiveness, so that Allah then teaches us through the Prophet Muhammad that the best of sinners are penitents/who ask for tawbah.

«Allah will keep firm those who believe, with the word that stands firm in this world (i.e. they will keep on worshipping Allah Alone and none else» Ibrahim:27

By knowing the Qur'an and reading tafseer, the soul becomes steadfast and confident in Allah, and in accepting God's judgment/Qadar. He will give thanks and praise if he is struck by bad things, and be patient if he is touched by harm. «It may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allah knows but you do not know». Since surrendering to Devine destiny/Qadar and believing in his all-knowing name is a good reward in life and the day oh judgment.

A .Prayer: that a person should leave whatever is in his hand to answer the call of Heaven in respect five times every day, as a break from worldly hardships, helps to relieve tension from the stresses of life..

b.Zakaah: in giving the right of the poor from your private money, it cleanses the heart from  love of money, and cultivates the virtue of giving or altruism.

C . Fasting/Sawm: At first, controlling desires! so when the Lord's command prevents you for hours, it is to teach you to pay attention and put a limit to your desire, and fasting also promotes a healthy feeling for homeless , the needy and the hungry.
