Frankincense (‘Lubbaan’ in Arabic) is an aromatic rasin produced by a certain genus of trees grown mainly in Yemen, Somalia and Oman, and is traditionally used in perfumes, incense and as a medicine. The resin is tapped and allowed to harden, before being powdered. It is most commonly very light yellow in colour and is discussed as one of the medicines used in the treatment of forgetfulness. [Page 337 of Healing with the Medicine of the Prophet (sallallahu alayhi wasallam) – Darussalam 2003]
The brothers at the TibbeNabawi.org site say that a ‘tea’ can be made by tying the frankincense resin in a small cloth like a piece of muslin, and adding it to boiling water. Let the water simmer for around 5 min before extracting the frankincense and allowing the tea to cool down before drinking.
Remedies for Forgetfulness which are substantiated by the Sunnah
Hijama
It was narrated by Jabir bin ‘Abdullah (rahimullah) that he paid Al-Muqanna a visit during his illness and said, “I will not leave till he gets cupped, for I heard Allah’s Apostle (sallallahu alayhi wasallam) saying, “There is healing in cupping [Hijama].”
Sahih al Bukhari Volume 7, Book 71, Number 600.
It was also narrated by Ibn Abbaas (radhi Allahu anhu) that the Prophet (sallallahu alayhi wasallam) was cupped on his head for an ailment he was suffering from while he was in a state of Ihram. at a water place called Lahl Jamal located on the road to Makkah. Ibn ‘Abbas further said: Allah s Apostle was cupped on his head for unilateral headache while he was in a state of Ihram.Sahih al Bukhari Volume 7, Book 71, Number 602
The Hijama practitioner should take extra care and not remove a lot of blood. The top middle part of the head (crown) is the Sunnah point – Sahih al Bukhari Vol. 3, Book 29, Hadith 62
Ruqyah
The established Hadith confirm that the Recitation of the Qur’an was performed by the Messenger of Allah (sallallahu alayhi wasallam) to treat people (mainly those inflicted with Magic or Evil Eye) and that there is no harm in reciting it yourself as long as it is only from the Qur’an;
A’isha (radhi Allahu anha) narrated that Allah’s Apostle (sallallahu alayhi wasallam) used to treat with a Ruqyah saying, “O the Lord of the people! Remove the trouble The cure is in Your Hands, and there is none except You who can remove it (the disease).”
Sahih al Bukhari Volume 7, Book 71, Number 640.
“My Lord! Expand for me my breast [with assurance]. Ease my task for me. Remove the knot [impediment] from my tongue. So that they may understand my speech.”[Qur’an 20:25-28]
