«اللهُمَّ اجْعَلْ لِي فِي قَلْبِي نُورًا، وَفِي لِسَانِي نُورًا، وَفِي سَمْعِي نُورًا، وَفِي بَصَرِي نُورًا، وَمِنْ فَوْقِي نُورًا، وَمِنْ تَحْتِي نُورًا، وَعَنْ يَمِينِي نُورًا، وَعَنْ شِمَالِي نُورًا، وَمِنْ بَيْنِ يَدَيَّ نُورًا، وَمِنْ خَلْفِي نُورًا، وَاجْعَلْ فِي نَفْسِي نُورًا، وَأَعْظِمْ لِي نُورًا»
{وهو دعاء يُشرع قوله في السجود خاصة في صلاة الليل}
Allahumma aj‘al lī fī qalbī nūran, wa fī lisānī nūran, wa fī sam‘ī nūran, wa fī baṣarī nūran, wa min fawqī nūran, wa min taḥtī nūran, wa ‘an yamīnī nūran, wa ‘an shimālī nūran, wa min bayni yadayya nūran, wa min khalfī nūran, wa aj‘al fī nafsī nūran, wa a‘ẓim lī nūran
“O Allah, place light in my heart, light on my tongue, light in my hearing, light in my sight, light above me, light beneath me, light to my right, light to my left, light in front of me, and light behind me. Place light within myself and grant me great light.”
(This supplication is prescribed for prostration, especially during Qiyām al-Layl.)
