اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا ، وَفِي لِسَانِي نُورًا ، وَاجْعَلْ فِي سَمْعِي نُورًا ، وَاجْعَلْ فِي بَصَرِي نُورًا ، وَاجْعَلْ مِنْ خَلْفِي نُورًا ، وَمِنْ أَمَامِي نُورًا ، وَاجْعَلْ مِنْ فَوْقِي نُورًا ، وَمِنْ تَحْتِي نُورًا ، اللَّهُمَّ أَعْطِنِي نُورًا
Translation 
O Allah, place within my heart light, and upon my tongue light, and within my ears light, and within my eyes light, and place behind me light, and in front of me light, and above me light, and beneath me light. O Allah, bestow upon me light.
Transliteration
allaahumma-j‛al fee qalbee noor-an, wa fee lisaanee noor-an, waj‛al fee sam‛ee noor-an, waj‛al fee baṣaree noor-an , waj‛al min khalfee noor-an, wamin amaamee noor-an, waj‛al min fawqee noor-an, wa min taḥtee noor-an, allahumma a‛ṭinee noor-an
