[Machine] Ibn Abbas said about the saying of Allah, "Obey Allah and obey the Messenger and those in authority among you" [Quran 4:59] - it means the people of knowledge and religion and the people of obedience to Allah who teach the people the noble aspects of their religion, command them to do good, and forbid them from evil. So, Allah has made it obligatory to obey them. These are the statements that indicate the necessity for scholars to be humble towards those whom they teach.  

عَنِ ابْنِ عَبَّاسٍ فِي قَوْلِهِ تَعَالَى {أَطِيعُوا اللَّهَ وَأَطِيعُوا الرَّسُولَ وَأُولِي الْأَمْرِ مِنْكُمْ} [النساء 59] يَعْنِي «أَهْلَ الْفِقْهِ وَالدَّيْنِ وَأَهْلِ طَاعَةِ اللَّهِ الَّذِينَ يُعَلِّمُونَ النَّاسَ مَعَالِيَ دِينِهِمْ وَيَأْمُرُونَهُمْ بِالْمَعْرُوفِ وَيَنْهَوْنَهُمْ عَنِ الْمُنْكَرِ فَأَوْجَبَ اللَّهُ طَاعَتَهُمْ» «وَهَذِهِ أَحَادِيثُ نَاطِقَةٌ بِمَا يَلْزَمُ الْعُلَمَاءُ مِنَ التَّوَاضُعِ لِمَنْ يُعَلِّمُونَهُمْ»
