Al-Ash'ari said, "Part of respect for Allah is to show respect to an old Muslim and to someone who knows the Qur'an, as long as he does not go to excess in it nor turn away from it, and to respect a just ruler."  

عَنِ الأَشْعَرِيِّ قَالَ إِنَّ مِنَ إِجْلاَلِ اللهِ إِكْرَامَ ذِي الشَّيْبَةِ الْمُسْلِمِ وَحَامِلِ الْقُرْآنِ غَيْرِ الْغَالِي فِيهِ وَلاَ الْجَافِي عَنْهُ وَإِكْرَامَ ذِي السُّلْطَانِ الْمُقْسِطِ  

Same as 354.  

قَالَ رَسُولُ اللهِ ﷺ لَيْسَ مِنَّا مَنْ لَمْ يَرْحَمْ صَغِيرَنَا وَيُوَقِّرْ كَبِيرَنَا
