The Prayer of Jabez is taken from 1 Chron 4:10. It is a signature prayer that is specifically catered to increase. However in the desire to gain more the prayer directs us not to cause others pain in our quest so that guilt would not prevail over our lives. The important thing to note in this prayer is that the request was already granted. So to when we pray God has already granted our request. It is for us now to receive it.
Prayer of Jabez
Oh that thou wouldest bless me indeed
and enlarge my coast and that thine hand
might be with me, and that thou wouldest
keep me from evil that it may not grieve me!
And God granted him that which he requested
