Is it permissible to pray the greeting of the mosque after the regular voluntary prayer?

Question:
He says: I entered the mosque and the prayer had already been called for, and I had not performed the greeting of the mosque. Is it permissible for me to perform it after the regular voluntary prayer?

Answer:
The obligatory prayer suffices for the greeting of the mosque. If you come and the prayer is being called for, or they are already praying, you join them, and it suffices for the greeting of the mosque; it becomes the obligatory prayer and the greeting of the mosque. Yes.
