Nowadays BGP sync is turned off, but why do you want BGP to sync with andIGP, what will then be the use of BGP, if the IGP also knows the route?

The use of BGP is to inject the route into IGP;

This is not the use of BGP. You do not want to inject your BGP routes into IGP unless you are doing something small scale like an MPLS VPN. The current BGP table size is above 450,000 routes! You don't want that in your IGP table.
The purpose of BGP is external reach ability. An IGP is for internal reach ability.

In short when synchronization is on :- we can only use IGP but when its off we can use both iBGP and IGP.
