[Machine] I heard the Messenger of Allah ﷺ saying, "O Allah, I ask you for beneficial knowledge and seek refuge in you from knowledge that is of no benefit." The wording is from Yunus.  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «اللهُمَّ إِنِّي أَسْأَلُكَ عِلْمًا نَافِعًا وَأَعُوذُ بِكَ مِنْ عِلْمٍ لَا يَنْفَعُ» اللَّفْظُ لِيُونُسَ  

[Machine] That the Messenger of Allah ﷺ used to supplicate saying, "O Allah, benefit me with what You have taught me and teach me what will benefit me and grant me knowledge that will benefit me."  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَدْعُو يَقُولُ «اللهُمَّ انْفَعْنِي بِمَا عَلَّمْتَنِي وَعَلِّمْنِي مَا يَنْفَعُنِي وَارْزُقْنِي عِلْمًا تَنْفَعُنِي بِهِ»
