(Is the below hadith Authentic or not. I saw this in one facebook post) Prophet Muhammad (salla Allahu alaihi wa sallam) said: Honey is a remedy for every illness and the Quran is a remedy for all illness of the mind, therefore I recommend to you both remedies, the Quran and honey. [Reference: Sahih al-Bukhari]
