Question:
May Allah reward you, Honorable Shaykh. A questioner says: In the book *al-Durar al-Saniyyah*, the phrase "the Shaykh's sons were asked" is sometimes mentioned. Who is meant by the Shaykh's sons?

Answer:
The sons of Shaykh Muhammad ibn 'Abd al-Wahhab are 'Abd Allah, 'Ali, and Ibrahim. These are the Shaykh's sons. I think the eldest is 'Ali, for may Allah have mercy on him, he was known as Abu 'Ali. The eldest is 'Ali, then 'Abd Allah, then Ibrahim, then Husayn. Yes, and al-Hasan. Yes, al-Hasan, who is Shaykh 'Abd al-Rahman ibn Hasan. Yes, al-Hasan and Husayn.
