How to improve memory:
Ali ibn Hashram, may Allah have mercy on him, said:
"I never saw a book in Waki's hands, the whole thing was in his memory, and I asked him about a remedy to improve memory, to which he said:" If I tell you about this medicine, will you use it?".
To which I said: "I swear by Allah"
He said: "Abandonment of sins, truly I did not find a cure for memory similar to it."
