Dua for Strengthening Memory

Dua for Strengthening Memory:

Glorified are You. We do not know except what you have taught us. Surely you are all-knowing, all-wise. My Lord, expand for me my Bosom and ease for me my task and remove the knot from my tongue (speech) so that they may understand my speech. My Lord increase me in knowledge.
O Allah, fill my heart with light and increase the strength of my hearing, my sight and my memory.
