Dr. Naasir ibn Misfir az-Zahraanee narrates:
Whenever it was mentioned to the Shaykh about those from the scholars who had passed away, especially those who were from amongst his close friends and scholars, he would be deeply affected. He would pray for them a lot and even cry and become upset by the news.
One day he spoke about his Shaykh, al-’Allaamah Muhammad ibn Ibraaheem (rahima-hullaah), but was unable to hold himself back from crying. I would sit beside him many times, whilst his assistant would read to us the fataawa of Shaykh Muhammad ibn Ibraaheem (rahima-hullaah), and in some instances Shaykh Muhammad ibn Ibraaheem (rahima-hullaah) would refute Shaykh Ibn Baaz himself, at which the Shaykh would smile and pray for him and ask Allaah to have mercy upon him.
