Du'a for a mother's obedience

اللَّهُمَّ اشْغَلْ قَلْبَهَا بِحُبِّكَ، وَلِسَانَهَا بِذِكْرِكَ، وَبَدَنَهَا بِطَاعَتِكَ

Allahummash-ghal qalbaha bihubbik, wa lisanaha bidhikrik, wa badanaha bita'atik

O Allah, occupy her heart with Your love, her tongue with Your remembrance, and her body with Your obedience.

A general supplication, not a narration from the Prophet (peace be upon him).
