"That a man should discipline his son is better for him than to have given a Sa' in charity."  

قَالَ رَسُولُ اللَّهِ ﷺ لأَنْ يُؤَدِّبَ الرَّجُلُ وَلَدَهُ خَيْرٌ مِنْ أَنْ يَتَصَدَّقَ بِصَاعٍ  

"There is no gift that a father gives his son more virtuous than good manners."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَا نَحَلَ وَالِدٌ وَلَدًا مِنْ نَحْلٍ أَفْضَلَ مِنْ أَدَبٍ حَسَنٍ
