Du'a for a father's happiness

اللَّهُمَّ أَسْعِدْ قَلْبَ أَبِي، وَاشْرَحْ صَدْرَهُ، وَأَرِحْ قَلْبَهُ، وَأَبْعِدْ عَنْهُ كُلَّ مَا يُحْزِنُهُ، وَأَطِلْ عُمْرَهُ

Allahumma as'id qalba abi, washrah sadrahu, wa arih qalbahu, wa ab'id 'anhu kulla ma yuhzinuhu, wa atil 'umrahu

O Allah, bring happiness to my father's heart, expand his chest, comfort his heart, keep away from him all that saddens him, and prolong his life.

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