Du'a for a father's light

اللَّهُمَّ اجْعَلْ لَهُ فِي قَلْبِهِ نُورًا، وَفِي لِسَانِهِ نُورًا، وَفِي سَمْعِهِ نُورًا، وَفِي بَصَرِهِ نُورًا، وَمِنْ تَحْتِهِ نُورًا، وَعَنْ يَمِينِهِ نُورًا، وَعَنْ شِمَالِهِ نُورًا، وَمِنْ بَيْنِ يَدَيْهِ نُورًا، وَمِنْ خَلْفِهِ نُورًا

Allahumma-j'al lahu fi qalbihi nura, wa fi lisanihi nura, wa fi sam'ihi nura, wa fi basarihi nura, wa min tahtihi nura, wa 'an yaminihi nura, wa 'an shimalihi nura, wa min bayni yadayhi nura, wa min khalfihi nura

O Allah, place light in his heart, light on his tongue, light in his hearing, light in his sight, light beneath him, light on his right, light on his left, light before him, and light behind him.

Adapted into the third person masculine from Ṣaḥīḥ Muslim 763.
