This is mind blowing

يَا أَيُّهَا النَّاسُ قَدْ جَاءَتْكُمْ مَوْعِظَةٌ مِنْ رَبِّكُمْ وَشِفَاءٌ لِمَا فِي الصُّدُورِ وَهُدًى وَرَحْمَةٌ لِلْمُؤْمِنِينَ

“People, indeed a reminder has come to you from your Lord, a cure for what is in the chests, a guide and a mercy for the faithful.” Qur’ān 10:57

In this verse Allāh describes the Qur'ān with four qualities:

1. A reminder
2. A cure
3. A guide
4. A mercy

To better understand that, think of the Qur'an as a doctor. A physician’s role varies based on the patient, the illness, and its severity. Sometimes, he takes preventative steps by warning a healthy person from things that may harm his health. If, however, the patient is already sick, then he reacts, moving from preventive care to treatment and cure. After a patient is healed, he takes on the role of a guide who prescribes what the patient needs to maintain health. Once the patient is healthy, he will recognize the blessings of following his doctor's advice.

Imām al-Rāzi notes that this is the role of the Qur’an in our lives: some of us are healthy and only need reminders; some of us are sick and need treatment; some of us are cured and need to maintain our health, and some of us are able to recognize the blessings of treatment.

Allah! Let us be maintained, treated, guided an appreciative of Your Book!
