Imam As-Sadiq (a.s.) said:
لَيْسَ مِنّا مَنْ لَمْيُوَفَّرْ كَبيرَنا وَ لَمْ يَرْحَمْ صَغيرَنا
One who does not respect the elders and does not show affection to the children, does not belong to us.1
Human societies are like an extensive caravan which is continuously moving. The infants are born and children grow up and adults become old and the old die and nobody is excepted from passing these stages.
The older ones are more experienced and have deeper insight . The conscientious ones among them have contributed to society through numerous services during their life. All this supports the argument that they should be respected by the youth and adolescents.
And since children are at the beginning stage of their life, tender, innocent and impressionable, they should be treated with love and affection . Foundations of their character and prosperity should be constructed lovingly by the adults . These are the ways and customs of a humanitarian and progressive society.
