"They ask you about the Ruh. Say:- The Ruh is from the command of my Lord-. Little is the knowledge that you have been given" (17:85).
The term is often used in Arabic language to indicate what makes bodies alive and therefore we may talk about specific mineral's ruh, vegetal's ruh, animal ruh, human's ruh, etc..
From the Qur'an we understand it is a creation that Allah attributes directly to Himself. For example it is said: "I am to create a man from clay. And when I have fashioned him and I have blown in him My spirit, then fall in prostration" (38:71-72). Here, the creation of the physical man (bashar) has been linked to clay but it was only after the blowing of the Ruh from the Almighty that the angels fell into prostration: "So the angels prostrated one and all" (38:73).
Some exegetes have also linked the Ruh to angelic forces or angels themselves.
With prayers for your success.
