Narrated by Anas (RA): The Messenger of Allah (ﷺ), used to say:

اَللَّهُمَّ انْفَعْنِيْ بِمَا عَلَّمْتَنِيْ وَعَلِّمْنِيْ مَا يَنْفَعُنِيْ وَارْزُقْنِيْ عِلْمًا تَنْفَعُنِيْ بِهِ

Allaahumman fa'ni bimaa allamtani wa allimni maa yanfauni war-zuqni ilman tanfauni bihi

O Allah! Grant me benefit in what you have taught me, and teach me useful knowledge and provide me with knowledge that will benefit me.
