If you pray the voluntary night prayer one hour before Fajr and sit waiting for the Fajr prayer, is this action valid?

Question:
If I pray the voluntary night prayer, meaning approximately one hour before the Fajr prayer, and I fear that if I sleep I will miss the Fajr prayer, so I remain awake after finishing my prayer waiting for the Fajr prayer, is this action valid?

Answer:
This is a great deed, or you pray from the last part of the night what you can, then you sit remembering Allah (Mighty and Majestic), seeking forgiveness, or reading the Qur'an, waiting for the Fajr prayer in this manner, and fearing sleep, meaning it is a continuation of the righteous deed, and waiting to perform the obligatory prayer, so you are excused and on good. Yes.

The presenter:
May Allah reward you with good, and may He do you good.
