اللَّهُمَّ إِنِّي أَسْتَوْدِعُكَ مَا قَرَأْتُ وَمَا حَفِظْتُ، فَرُدَّهُ إِلَيَّ عِنْدَ حَاجَتِي إِلَيْهِ
Allahumma inni astawdi'uka ma qara'tu wa ma hafizt, faruddahu ilayya 'inda hajati ilayh
O Allah, I entrust to You what I have read and memorized, so return it to me when I need it.

O Allah, there is no ease except what You make easy, and You make difficulty easy if You will.
My Lord, increase me in knowledge.
My Lord, expand for me my chest, ease for me my task, and untie the knot from my tongue so they may understand my speech.
O Ever-Living, O Sustainer, by Your mercy I seek help.
O Allah, benefit me by what You have taught me, teach me what benefits me, and increase me in knowledge.
O Allah, make me content with Your decree and bless me in what has been destined for me.
