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

اللَّهُمَّ اكْفِهِ بِحَلَالِكَ عَنْ حَرَامِكَ، وَأَغْنِهِ بِفَضْلِكَ عَمَّنْ سِوَاكَ

Allahummak-fihi bihalalika 'an haramik, wa aghnihi bifadlika 'amman siwak

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

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