Du'a for a father's Paradise

اللَّهُمَّ ارْزُقْ أَبِي الْجَنَّةَ وَمَا قَرُبَ إِلَيْهَا مِنْ قَوْلٍ وَعَمَلٍ، وَبَاعِدْ بَيْنَهُ وَبَيْنَ النَّارِ وَمَا قَرُبَ إِلَيْهَا مِنْ قَوْلٍ وَعَمَلٍ

Allahummar-zuq abil-jannata wa ma qaruba ilayha min qawlin wa 'amal, wa ba'id baynahu wa baynan-nari wa ma qaruba ilayha min qawlin wa 'amal

O Allah, grant my father Paradise and whatever words or actions bring him near to it, and distance him from the Hellfire and whatever words or actions bring him near to it.
