Be grateful to your parents. It is among the cardinal principles of good manners and acknowledgement of debt that one should be grateful for all the acts of kindness one has received. It is a fact that the main reason for our physical existence are our parents. We grow up under their tender care and reach adulthood. They suffer great hardships and show extraordinary love and suffer unparalleled sacrifices in bringing us up and it is, therefore, befitting that we should be grateful to the from the core of our hearts. This is why Allah had decreed that we should render thanks to Him, we should express gratitude to our parents as well.
“(We have decreed) that you should render thanks unto Me and unto your parents.” (31:14)
