This is another very rare acquisition of a leather prayer mat from Somalia. I 
was told it is from 15th Century CE and been passed down though 
generations. This prayer mat is made of leather and had been sewn 
together from pieces.
The use of this skin prayer mat is very popular among the Sufis and 
religious people especially in Somalia and Etiopia. In a book, Islam in 
Etiopia written by J. Spencer Trimingham. he mentioned about the 
activity of Tariqa or Sufi movements in Somalia and Etiopia especially 
in 18th & 19th Century. During the initiation ritual between the
 leader of the Tariqa movement ( Khalifa) and the novice, one of the 
items that will be given to the new member is a Sijjada which is a piece
 of skin prayer mat which he carries about on his shoulder.
In the book : The Mad Mullah of Somaliland by 
Douglas Jardine, there is a mention of  an outcast tribe in Somalia 
especially  Midgan that making a leather prayer by cutting it in the 
shape of the mosque at Mecca.
From FAO website, there are a few goat species in 
Somalia whom skins are made into prayer mat. Haraghe Highland is the 
small size goat that has main color of plain non spotted white and some 
with black and brown. The prayer mat is called
Sijaja.
Another species of goat is short-eared Somali ( 
Denghier) which has a medium size and widely used to make sleeping mats 
and prayer mats. The color of the coat is mainly white 76 % with some 
brown, black and grey.
The third specie is Long-eared Somali ( 
Galla/Melebo) which is bigger than short-eared Somali. The coat color is
 almost completely white with tiny colors in brown, black and grey. The 
skin is widely used as a sitting mat and prayer mat.
They are called Harek or Okedi in Somalian landuage.  
In a writing to CNN, The author,  Dr Cawo Abdi recollected her memory of
 sitting on her father’s prayer mat made from goat skin somewhere in 
central Somalia whom they belonged to Nomadic hamlets.Her father was a 
Quranic teacher that teach
children from hamlet to hamlet.
