Allah said that his Prophet Ibrahim (peace be upon him) said, “And He feeds me and quenches my thirst And when I fall sick then He (Allaah) cures me.” [Surah Shu’araa: 80] Some scholars of Tafseer explain that there is a relation between what we eat and drink and falling sick since most people fall ill because of their diet. This could be a reason why Allah mentioned that Ibrahim (peace be upon him) recognized that Allaah is the One who provides sustenance for us but that sickness is due to our own self and this is why sickness is mentioned after food and drink in this Verse. “And We sent down of the Qur’an that which is a healing and a mercy to those who believe.” [Soorah Israa: 82] A healing to ‘those who believe” showing the importance of rectifying our belief and actions such that we are true believers if we want the Qur’an to benefit us. Ayub (peace be upon him) called upon his Lord, “And remember Ayub when he cried to his Lord: Verily, distress has seized me, and You are the Most Merciful of all those who show mercy.” [Soorah al-Anbiyaa: 83] When he was inflicted with harm. And the reply came from his lord: “We answered him and removed the distress that was on him…” [Soorah al-Anbiyaa: 84] “O mankind! There has come to you a good advice from your Lord (Qur’an) enjoining all that is good and forbidding all that is evil, and a healing for that which is in your breasts, a guidance and a mercy for the believers.” [Soorah Yunus: 57]
This shows us that the Qur’an has four benefits:
A good advice, Cure for our hearts from all diseases, Guidance, Mercy for mankind. “Say: it (the Qur’an) is a healing for those who believe, a guide and healing…” [Soorah Fusilaat: 44] The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “There is no-one who is afflicted by distress and grief, and says: ‘Allaahumma inni ‘abduka ibn ‘abdika ibn amatika naasiyati bi yadika, maada fi hukmika, ‘adlun fiy qadaa’ika. As’aluka bi kulli ismin huwa laka sammayta bihi nafsaka aw anzaltahu fi kitaabika aw ‘allamtahu ahadan min khalqika aw ista’tharta bihi fi ‘ilm il-ghayb ‘indaka an taj’al al-Qur’aana rabee’ qalbi wa noor sadri wa jalaa’ huzni wa dhihaab hammi (O Allaah, I am Your slave, son of Your male and female slave, my forelock is in Your hand, Your command over me is forever executed and Your decree over me is just. I ask You by every name belonging to You which You have named Yourself with, or revealed in Your Book, or You taught to any of Your creation, or You have preserved in the knowledge of the Unseen with You, that You make the Qur’an the harvest of my heart and the light of my chest, and a departure for my sorrow and a release for my anxiety), but Allaah will take away his distress and grief, and replace it with joy.” He was asked: “O Messenger of Allaah, should we learn this?” He said: “Of course; everyone who hears it should learn it.”[Ahmad 1/391–Al-Albani graded it authentic] “And if Allaah tests you with affliction, there is none who can remove it but He…” [Soorah Yunus: 107] “And He will give you victory over them and heal the breasts of a believing people.” [Soorah Tawbah: 14].
