أرْبَعٌ مَنْ اُعْطِيَهُنَّ فَقَدْ اُعْطِيَ خَيْرَ الدُّنْيا وَالآخِرَةِ : صِدْقُ حَديث، وَأداءُ أمانَة، وَ عِفَّةُ بَطْن، وَ حُسْنُ خُلق
Four virtues, whoever has them will have the good of this world and the afterworld: honesty of speech, rendering of trusts (being trustworthy), eating from lawful sources, and possessing good manners.
This quote summarized four important virtues to be perfected by a Muslim in his lifetime. Follow these links to know more about them:
ثلاث لا يستحيى منهن: خدمة الرجل ضيفه وقيامه عن مجلسه لأبيه ومعلمه و طلب الحق وإن قل
Three acts are not considered demeaning: serving your guest, vacating your seat to your father or your teacher, and demanding your rights no matter how small they might be.
In social gatherings in ancient Arabia (and maybe still to this day), your position or seat in the gathering depends on your social status. Leaving your seat to someone who just joined the gathering is considered a respectful act.
The Imam is telling us that these three acts are not shameful or degrading. Being polite and kind to others and demanding your rights are therefore good habits to have.
