The factors that helped the Shaykh acquire knowledge despite the loss of sight

Question:
Your Eminence the Shaykh, it is well known from your biography that you lost your sight from a young age, and yet you reached a great height in knowledge. What did you rely on, after Allah, to reach the level of knowledge you attained?

Answer:
I learned first while I was still seeing. I was born in Dhul-Hijjah in the year 1330 of the Hijrah, and I began learning after the age of ten, eleven, or twelve. I completed the Qur'an and then focused on memorizing it. I studied under the shaykhs while I was young, before my sight failed, with our shaykh, Shaykh Salih ibn 'Abd al-'Aziz al-Shaykh, our shaykh, Shaykh Muhammad ibn 'Abd al-Latif al-Shaykh, Shaykh Hamd ibn Faris, and Shaykh Sa'd ibn 'Atiq. Then I studied with our shaykh, Shaykh Muhammad ibn Ibrahim (may Allah have mercy on him), in the fifth decade of the fourteenth century, while I was still seeing. I memorized a number of texts while I was seeing. Then the illness began in the eye in the year 1346, which was when I was sixteen.
My sight went in the first year of 1350, when I was nineteen. When my sight went and I was nineteen years old, I had already memorized a number of texts and studied a number of texts in 'aqidah and other subjects while I was seeing, and I wrote things while I was seeing, praise be to Allah. Then I completed my studies after the loss of sight until the year 1357. I was appointed to the judiciary in the year 1357, in the last of the first and last groups, in the year 1357 in the al-Kharj region. I stayed there for fourteen years in al-Kharj, during which I organized circles of knowledge, and a group of students from the sons of Najd and others studied with me. Then I returned to Riyadh at the end of the year and began studying at the Scientific Institute in Riyadh in the year [1357], then at the College of Sharia in the year [1358] to the year 1380, and its classes at the college, from which a large number of students graduated, in the year 1376 and after. Then I was appointed at the Islamic University and began working there as its director in the year 1381, and I remained there until the end of the year 1395. Then I transferred from there in Shawwal of the year 1395 to the Department of Ifta, in Shawwal of the year 1395, to this day. I also organized circles in the city, circles for the people of the city.
In the Prophet's Mosque during his stay there. Along with the classes I conduct for students at the College of Sharia, the College of Hadith at the University, and the College of Da'wah.
Then, after my return to Riyadh in Shawwal of the year 1395, I organized the classes in Riyadh, praise be to Allah. We ask Allah to accept our work and to guide us to all beneficial knowledge and righteous deeds. The classes and the scholarly circles have continued to this day in Riyadh, from the time I arrived in Riyadh to this day, along with the previous classes in Riyadh.
