[Machine] "Whoever among you possesses knowledge, let them spread it, and whoever does not possess knowledge, let them say, 'I do not know, Allah knows best.' Indeed, when a learned person is asked about something they do not know, they will say, 'Allah knows best.' And Allah has said to his Messenger, 'Say, I do not ask you for any reward for this [Quran], nor am I a pretentious person.'" [Surah Al-An'am, 86]  

الدارمي:١٧٩أَخْبَرَنَا جَعْفَرُ بْنُ عَوْنٍ عَنِ الْأَعْمَشِ عَنْ مُسْلِمٍ عَنْ مَسْرُوقٍ عَنْ عَبْدِ اللَّهِ قَالَ

مَنْ عَلِمَ مِنْكُمْ عِلْمًا فَلْيَقُلْ بِهِ وَمَنْ لَمْ يَعْلَمْ فَلْيَقُلْ لِمَا لَا يَعْلَمُ اللَّهُ أَعْلَمُ فَإِنَّ الْعَالِمَ إِذَا سُئِلَ عَمَّا لَا يَعْلَمُ قَالَ اللَّهُ ﷻ أَعْلَمُ وَقَدْ قَالَ اللَّهُ لِرَسُولِهِ {قُلْ مَا أَسْأَلُكُمْ عَلَيْهِ مِنْ أَجْرٍ وَمَا أَنَا مِنَ الْمُتَكَلِّفِينَ} [ص 86]
