Ibn Taymiyah رحمه الله narrates: I was once afflicted with an illness, upon which the doctor said to me, “Your studying and indulgence in ‘ilm further aggravates the illness.”
So I said to him, “I cannot bear that, and I will appeal to you using your own knowledge. Does not a person’s condition strengthen somewhat when he/she is happy and relaxed; and consequently speed up the healing process?”
He replied, “Of course.”
I said, “I become happy engrossed in knowledge, and my condition strengthens with it, so I find contentment through it.”
He remarked, “This is beyond our treatment procedures!”[1]
