In the Qur'an there are 5 holy books mentioned.
Qur'an Injiil Tawrat Zabur Sukhuf
To some degree I am aware that injiil is the bible and Tawrat is the old testament. My question is,what book is Zabur and Sukhuf? Also why are they almost unknown compared to the other three?
Edit:Tawrat correct spelling is Torah..
First of all, to get technical the tawrat is the Torah.
As for Zabur (Supposidly written by David) and sukhuf (written by Noah).
The Sukhuf is said to be lost a long time ago, thus it is unknown, and the physical existence of Zabur is never mentioned because it is also considered to be corrupted and lost. However many consider the Zabur to be equivalent to the biblical Psalms.
I live in a muslim society, so I know some of these stuff, might be wrong though.
