Dua to be recited on the twenty nineth day of Ramadhan

اللَّهُمَّ غَشِّنِي فِيهِ بِالرَّحْمَةِ وَ ارْزُقْنِي فِيهِ التَّوْفِيقَ وَ الْعِصْمَةَ وَ طَهِّرْ قَلْبِي مِنْ غَيَاهِبِ التُّهَمَةِ يَا رَحِيما بِعِبَادِهِ الْمُؤْمِنِينَ

O Allah, on this day, cover me with Your mercy, grant me in it success and protection, purify my heart from the darkness of false accusations, O the Merciful to His believing servants.
