Shaikh Abdul-Muhsin ibn Hamad al-Abbaad al-Badr said about Shaikh Ibn Baaz, may Allaah have mercy on him:

“And I also remember that when he went to Qasim in 1385ah to get married there, I was with the Shaikhs who went along with him. On the way there we were passing through a valley [and I recall it was one] which had trees and half way through the day a solar eclipse occurred. So he led us in the eclipse prayer in that valley, may Allaah have mercy on him.”

“And I remember one year when I was at the Islamic University of Medinah I entered the Prophet’s Mosque with him after they had called the adhaan for the midday prayer, and I was next to him.

So he prayed four rak’ahs and I prayed two.

And it is known that the supererogatory prayers [Sunan ar-Raatibah] are ten in number and that praying twelve is more complete. So when I gave salaam he turned towards me and said, “You only prayed two rak’ahs.” I said, “Yes.” So he said, “Praying twelve is more complete and greater in excellence.”

“… and he performed Hajj forty-seven times, may Allaah have mercy on him …”
