Is it permissible for a student of knowledge to supplicate with the words: "My Lord, forgive me, and bestow upon me knowledge that no one after me should possess, verily You are the Bestower"?

The supplication mentioned falls under the category of transgression in supplication ( الاعتداء في الدعاء) due to the impossibility of its fulfillment. Ibn Hajar clarified that transgression includes requesting something that is legally impossible. Al-Tibi added that transgression occurs by inclining towards excess or deficiency in supplication, whether for oneself or for others.
