The Eighteenth Day Supplication
اَللّٰهُمَّ نَبِّهْنِي فِيْهِ لِبَرَكَاتِ اَسْحَارِهِ
allahumma nabbhny fihi libarakati asharihi
O Allah; on this day, (please) attract my attention to the blessings at the last hours of night;
وَ نَوِّرْ فِيْهِ قَلْبِي بِضِيَاءِ اَنْوَارِهِ
wa nawwr fihi qalby bidya‘i anwarihi
And enlighten my heart with the glow of its light;
وَ خُذْ بِكُلِّ اَعْضَائِي اِلَى اتِّبَاعِ آثَارِهِ
wa khudh bikulli a`daiy ila attba`i atharihi
And lead all my organs to the following of its traces;
بِنُوْرِكَ يَا مُنَوِّرَ قُلُوْبِ الْعَارِفِيْنَ
binurika ya munawwra qulubi al`arifina
