that the Messenger of Allah ﷺ said: "Indeed Allah does not take away knowledge by removing it from the people, but He takes away knowledge by taking the scholars, until there remains no scholar and the people begin to ask the ignorant leaders, so they give their verdict without knowledge. They will go astray and lead the people astray."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ لاَ يَقْبِضُ الْعِلْمَ انْتِزَاعًا يَنْتَزِعُهُ مِنَ النَّاسِ وَلَكِنْ يَقْبِضُ الْعِلْمَ بِقَبْضِ الْعُلَمَاءِ حَتَّى إِذَا لَمْ يَتْرُكْ عَالِمًا اتَّخَذَ النَّاسُ رُءُوسًا جُهَّالاً فَسُئِلُوا فَأَفْتَوْا بِغَيْرِ عِلْمٍ فَضَلُّوا وَأَضَلُّوا وَفِي الْبَابِ عَنْ عَائِشَةَ وَزِيَادِ بْنِ لَبِيدٍ  

from Abu Ad-Darda who said: "We were with the Prophet ﷺ when he raised his sight to the sky, then he said: 'This is the time when knowledge is to be taken from the people, until what remains of it shall not amount to anything." So Ziyad bin Labid Al-Ansari said: 'How will it be taken from us while we recite the Qur'an. By Allah we recite it, and our women and children recite it?' He ﷺ said: 'May you be bereaved of your mother O Ziyad! I used to consider you among the Fuqaha of the people of Al-Madinah. The Tawrah and Injil are with the Jews and Christians, but what do they avail of them?'" Jubair said: "So I met 'Ubadah bin As-Samit and said to him: 'Have you not heard what your brother Abu Ad-Darda said?' Then I informed him of what Abu Ad-Darda said. He said: 'Abu Ad-Darda spoke the truth. If you wish, we shall narrated to you about the first knowledge to be removed from the people: It is Khushu', soon you will enter the congregational Masjid, but not see any man in it with Khushu'.'"  

كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فَشَخَصَ بِبَصَرِهِ إِلَى السَّمَاءِ ثُمَّ قَالَ هَذَا أَوَانٌ يُخْتَلَسُ الْعِلْمُ مِنَ النَّاسِ حَتَّى لاَ يَقْدِرُوا مِنْهُ عَلَى شَيْءٍ فَقَالَ زِيَادُ بْنُ لَبِيدٍ الأَنْصَارِيُّ كَيْفَ يُخْتَلَسُ مِنَّا وَقَدْ قَرَأْنَا الْقُرْآنَ فَوَاللَّهِ لَنَقْرَأَنَّهُ وَلَنُقْرِئَنَّهُ نِسَاءَنَا وَأَبْنَاءَنَا فَقَالَ ثَكِلَتْكَ أُمُّكَ يَا زِيَادُ إِنْ كُنْتُ لأَعُدُّكَ مِنْ فُقَهَاءِ أَهْلِ الْمَدِينَةِ هَذِهِ التَّوْرَاةُ وَالإِنْجِيلُ عِنْدَ الْيَهُودِ وَالنَّصَارَى فَمَاذَا تُغْنِي عَنْهُمْ قَالَ جُبَيْرٌ فَلَقِيتُ عُبَادَةَ بْنَ الصَّامِتِ قُلْتُ أَلاَ تَسْمَعُ إِلَى مَا يَقُولُ أَخُوكَ أَبُو الدَّرْدَاءِ فَأَخْبَرْتُهُ بِالَّذِي قَالَ أَبُو الدَّرْدَاءِ قَالَ صَدَقَ أَبُو الدَّرْدَاءِ إِنْ شِئْتَ لأُحَدِّثَنَّكَ بِأَوَّلِ عِلْمٍ يُرْفَعُ مِنَ النَّاسِ الْخُشُوعُ يُوشِكُ أَنْ تَدْخُلَ مَسْجِدَ جَمَاعَةٍ فَلاَ تَرَى فِيهِ رَجُلاً خَاشِعًا
