Du'a for a mother's independence from the unlawful

اللَّهُمَّ اكْفِهَا بِحَلَالِكَ عَنْ حَرَامِكَ، وَأَغْنِهَا بِفَضْلِكَ عَمَّنْ سِوَاكَ

Allahummak-fiha bihalalika 'an haramik, wa aghniha bifadlika 'amman siwak

O Allah, suffice her with Your lawful against Your prohibited, and make her independent of all those besides You by Your bounty.

Adapted into the third person feminine from Sunan al-Tirmidhī 3563.
