In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Al-Hassan (Ibn Abi Bakr An-Naysaabooree), may Allah have mercy upon him, narrated:

A Faqee [a scholar who truly fears Allah and has sound understanding of the religion] used to repeat lessons in his house many times. So, an old woman in his house said to him, “Indeed, I have memorised it myself!!” He he said, “Repeat it to me?” She repeated it. After a few days he said, “O old woman! Repeat that lesson now”. She said, “I didn’t memorise it”. He said, “As for me, I repeat what I have memorised to protect myself from what has afflicted you”.
