What is the interpretation and meaning of the Prophet Muhammad's (peace be upon him) saying: "Stay with her, for Paradise is at her feet"? And what are the forms of disobeying one's parents?

The Hadith: "Adhere to her leg, for there is Paradise," was narrated by Ibn Majah and others, and authenticated by Al-Albani. Its meaning is to adhere to obeying her and to be humble towards her, for that is a cause for entering Paradise. This is a metaphor for the utmost submission and humility towards them both. Disobeying one's parents is to sever ties with them and to disobey them in matters that are not sinful. It is manifested in defying them, not doing good to them, disobeying their commands, or rejecting their requests if one is able to fulfill them and it causes no harm.
