It was reported by Ibn al Qayyim in his book: "Rawdatul Muhibeen", I was informed by my Sheikh (Ibn Taymiyyah), he said: When I became sick the doctor said to me: Verily your research and Islamic lecturing increases your illness. I (Ibn Taymiyyah) replied: I can not stop, and I will debate you in your knowledge! If a person becomes happy and joyful doesn't this strengthen their soul or spirit, and as a result wards off illness? The doctor responded: Of course. So I (Ibn Taymiyyah) said: Verily my spirit is pleased with knowledge and it strengthens my nature and due to that I find relaxation. The doctor responded: This is something our knowledge doesn't apply to.
It was reported by Sheikh Muhammed bin Hadee to some of his visitors that he was told a story by Ahmed Al Hakimy, the brother of Sheikh Hafith Al Hakimy:
One year while Sheikh Hafith Al Hakimy was on Hajj or during Ramadan in Mecca, he was looking for the book titled: "Creation of The Servant's Action" by Imam Al Bukhari. While in Mecca he was informed that someone had arrived from India with a copy of the book and that he had given it to the library there in The Haram. Sheikh Hafith visited the library and requested to borrow the book under the condition that he would not leave the Haram and that he would return the book the following day after the rising of the sun. He took the book and requested for someone to bring him paper and a pen. He sat and made his own copy of the book. Then he continued to memorize the book until Fajr. After Fajr he rested for a short period of time and then woke up. Upon waking, he returned the original book to the library and said: Here is your original, and here is an extra copy (the copy he himself wrote) and the book is in my head (memorized).
May Allah grant Sheikh Hafith Al Hakimy ease in his grave and raise him with the righteous ameen
