DMX's family's going to hold a prayer vigil at the New York hospital where he's still clinging to life.
The rapper's family announced the gathering will take place Monday at 5 PM ET outside of the White Plains Hospital, where on Sunday night ... staff members held a small vigil of their own.
As we reported ... DMX's fiancee and mother have both been allowed to visit him in the ICU, where he remains on life support following the heart attack he suffered during an overdose Friday night.
We're told some of his kids are also flying in to see him, and family members are holding out hope that he's going to pull through despite our sources saying he has limited brain function and it does not look good.
For now though, everyone close to DMX is simply asking for prayers.
