Dua to be recited on the fourth day of Ramadhan

اللَّهُمَّ قَوِّنِي فِيهِ عَلَى إِقَامَةِ أَمْرِكَ وَ أَذِقْنِي فِيهِ حَلاوَةَ ذِكْرِكَ وَ أَوْزِعْنِي فِيهِ لِأَدَاءِ شُكْرِكَ بِكَرَمِكَ وَ احْفَظْنِي فِيهِ بِحِفْظِكَ وَ سِتْرِكَ يَا أَبْصَرَ النَّاظِرِينَ

O Allah, on this day, strengthen me in carrying out Your commands, let me taste the sweetness of Your rememberance, grant me, through Your graciousness, that I give thanks to You. Protect me, with Your protection and cover, O the most discerning of those who see.
