اللّهُـمَّ اجْعَـلْ فِي قَلْبـي نُوْرًا
وَفِي لِسَـانِي نُوْرًا
وَاجْعَـلْ فِي سَمْعِي نُوْرًا
وَاجْعَـلْ فِي بَصَرِي نُوْرًا
وَاجْعَـلْ مِنْ خَلْفِي نُوْرًا
وَمِنْ أَمَامِـي نُوْرًا
وَاجْعَـلْ مِنْ فَوْقِـي نُوْرًا
وَمِن تَحْتِـي نُوْرًا
اللّهُـمَّ أَعْطِنِـي نُوْرًا
Allahumma-j'al fi qalbi nura, wa fi lisani nura, waj'al fi sam'i nura, waj'al fi basari nura, waj'al min khalfi nura, wa min amami nura, waj'al min fawqi nura, wa min tahti nura, Allahumma a'tini nura.
