The wisdom behind saying "Subhan Rabi al-Azim" in the bowing and "Subhan Rabi al-A'la" in the prostration.

The Shaykh : And in this prostration, one says "Subhan Rabi al-A'la." What is the wisdom behind saying "Subhan Rabi al-Azim" in the bowing and "Subhan Rabi al-A'la" in the prostration? The wisdom is that bowing is an act of magnification, so it is fitting to say "Subhan Rabi al-Azim" (Glory be to my Lord, the Magnificent). As for prostration, it is a descent, so it is fitting to say "Subhan Rabi al-A'la" (Glory be to my Lord, the Most High), meaning the One who is free from descent and lowness. He, (Exalted and Majestic is He), is the Most High, meaning above everything. We have established this in the previous lesson, in the time between the tarawih prayer and the tahajjud prayer.
