Dua to be recited on the twenty first day of Ramadhan

اللَّهُمَّ اجْعَلْ لِي فِيهِ إِلَى مَرْضَاتِكَ دَلِيلاً وَ لا تَجْعَلْ لِلشَّيْطَانِ فِيهِ عَلَيَّ سَبِيلاً وَ اجْعَلِ الْجَنَّةَ لِي مَنْزِلاً وَ مَقِيلاً يَا قَاضِيَ حَوَائِجِ الطَّالِبِينَ

O Allah, on this day, show me the way to win Your pleasure, do not let Shaytan have a means over me, make Paradise an abode and a resting place for me, O the One who fulfills the requests of the needy.
