Is supplicating for strong memory and sharp intelligence to improve one's studies and speed of comprehension and memorization considered an transgression in supplication, and should one cease doing so?

A servant's supplication to his Lord to grant him strong memory, intelligence, and memorization is not an transgression in supplication, as it does not involve any violation of a religious command or a cosmic law. Among what has been reported from the Sovereigns regarding this is that Ibn Hajar drank Zamzam water to reach Al-Dhahabi's level of memorization, and he attained it and surpassed it.
