What is the meaning of the Hadith: "Whoever says, when he wakes up in the morning and when he enters the evening, 'Subhan Allah wa bihamdih' (Glory be to Allah and praise be to Him) one hundred times, and 'Subhan Allah al-Azim' (Glory be to Allah, the Most Magnificent) one hundred times," and does it mean a total of two hundred remembrances in a single day?

The wording mentioned in the question was not reported from the Prophet, peace and blessings be upon him. Rather, he said: "Two words that are light on the tongue, heavy in the scales, beloved to the Most Merciful: Subhanallah al-Azeem, Subhanallah wa bihamdihi (Glorified be Allah, the Most Magnificent; Glorified be Allah and praised be He)." This dhikr (remembrance) is absolute, not restricted by number or time.

It was authentically reported from him, peace and blessings be upon him, that he said: "Whoever says when he wakes up in the morning and when he enters the evening: Subhanallah wa bihamdihi (Glorified be Allah and praised be He) one hundred times, no one will come on the Day of Resurrection with anything better than what he came with, except for one who said the same as he did or more." This hadith is restricted to "Subhanallah wa bihamdihi."

As for the wording closest to the question, it is: "Whoever says when he wakes up in the morning and when he enters the evening: Subhanallah al-Azeem wa bihamdihi (Glorified be Allah, the Most Magnificent, and praised be He) one hundred times, no one will come on the Day of Resurrection with anything better than what he came with, except for one who said the same as he did or more." This indicates the permissibility of saying it in full.

The matter is broad, so it is permissible to suffice with "Subhanallah wa bihamdihi" one hundred times, or to say "Subhanallah al-Azeem wa bihamdihi" one hundred times, or "Subhanallah wa bihamdihi Subhanallah al-Azeem" one hundred times. It is best to perform acts of worship and adhkar (remembrances) with all the reported formulations.

"Subhanallah" means glorifying Allah from every imperfection, and "wa bihamdihi" means praising Him with attributes of perfection. The name of Allah "Al-Azeem" means the Possessor of Magnificence and Majesty. The saying "Subhanallah wa bihamdihi" is one of the most comprehensive forms of dhikr because it includes the meanings of glorification, tahlil (saying La ilaha illallah), tahmid (praising Allah), and takbir (saying Allahu Akbar).
