It was narrated from Jabir that :
the Messenger of Allah said: "Ask Allah for beneficial knowledge and seek refuge with Allah from knowledge that is of no benefit."

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ أُسَامَةَ بْنِ زَيْدٍ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " سَلُوا اللَّهَ عِلْمًا نَافِعًا وَتَعَوَّذُوا بِاللَّهِ مِنْ عِلْمٍ لاَ يَنْفَعُ " .
