from his father that he heard the Messenger of Allah ﷺ saying: "Whoever seeks knowledge to contend with the scholars, or to use it to argue with the fools, and to have people's faces turn towards him, then he shall be admitted to the Fire."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ طَلَبَ الْعِلْمَ لِيُجَارِيَ بِهِ الْعُلَمَاءَ أَوْ لِيُمَارِيَ بِهِ السُّفَهَاءَ أَوْ يَصْرِفَ بِهِ وُجُوهَ النَّاسِ إِلَيْهِ أَدْخَلَهُ اللَّهُ النَّارَ  

that the Prophet ﷺ said: "Whoever learns knowledge for other than (the sake of) Allah, or intends by it other than Allah, then let him take his seat in the Fire."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ تَعَلَّمَ عِلْمًا لِغَيْرِ اللَّهِ أَوْ أَرَادَ بِهِ غَيْرَ اللَّهِ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ وَفِي الْبَابِ عَنْ جَابِرٍ
