Reference: al-Imaam Ibn Baaz – Duroos wa Mawaaqif wa ‘Ibar – page 27
Ahmad ibn ‘Abdil-‘Azeez ibn Baaz – the Shaykh’s son – informed me:
I would read to my father, and when I had finished reading, or the car had stopped [since we had arrived at our destination] – sometimes if we were in a hurry, I would forget the page number. So when we would [later] return, the Shaykh would say:
Open [the book and read].
And I would say I have forgotten the page number. And the Shaykh would say:
[We are on] such-and-such a page.
