What is the mitzvah of doing what your parents tell you And when am I obligated and when not. Thank you.
Whenever a parent expresses a need or desire for something, there is an obligation upon the son to carry out his parent’s request. This is generally related to matters of serving a parent: Feeding him etc. The obligation does not include laying out money for parents, but naturally it is proper to do so where required and where this is not a heavy financial burden.
Authorities dispute the question of honoring a parent’s request where there is no concrete benefit to the parent. In this case (for instance a parent who instructs his son to wear a coat outside). In this case, it is still correct to comply, in particular where noncompliance will cause the parent to feel bad or to take offence.
