وَعَنْ أَنَسٍ رضى الله عنه
قَالَ: «كَانَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «اَللَّهُمَّ اِنْفَعْنِي بِمَا عَلَّمْتَنِي، وَعَلِّمْنِي مَا يَنْفَعُنِي، وَارْزُقْنِي عِلْمًا يَنْفَعُنِي»
The Messenger of Allah (sallallahu alayhi wa sallam) used to say, “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.” Related by An-Nasai and Al-Hakim.
