Du'a for a father's devotion

اللَّهُمَّ اجْعَلْهُ مِنَ الذَّاكِرِينَ لَكَ وَالشَّاكِرِينَ لَكَ

Allahumma-j'alhu min adh-dhakirina laka wash-shakirina lak

O Allah, make him among those who remember You and are thankful to You.

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