وَعَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ اللَّهَ لَا يَقْبِضُ الْعِلْمَ انْتِزَاعًا يَنْتَزِعُهُ مِنَ الْعِبَادِ وَلَكِنْ يَقْبِضُ الْعِلْمَ بِقَبْضِ الْعُلَمَاءِ حَتَّى إِذَا لَمْ يُبْقِ عَالِمًا اتَّخَذَ النَّاسُ رُءُوسًا جُهَّالًا فَسُئِلُوا فَأَفْتَوْا بِغَيْرِ عِلْمٍ فضلوا وأضلوا»
Abdallah ibn Amr reported God’s messenger as saying, “God does not take away knowledge by removing it from men, but takes it away by taking away the learned, so that when He leaves no learned man, men will take ignorant men as leaders. Causes will be presented to them and they will pass judgement without knowledge, erring and leading others into error.”
