The verse above (Q. 17.23) warns against insulting parents. In this verse, Allah commands people to worship Him alone and not to associate any partners with Him. Then, Allah mentions the importance of treating parents with kindness and respect. Insulting parents is a grave sin because they have given life, raised, and taken care of their children, and they deserve to be treated with love and respect. Therefore, the verse serves as a reminder to honor and respect parents and to refrain from insulting them.
