This is the recommended prayer on the fifth day of the holy month of Ramadan.
بسم الله الرحمن الرحیم
اللهمّ اجْعَلْنی فیهِ من المُسْتَغْفرینَ واجْعَلْنی فیهِ من عِبادَک الصّالحینَ القانِتین واجْعَلْنی فیهِ من اوْلیائِک المُقَرّبینَ بِرَأفَتِک یا ارْحَمَ الرّاحِمین
O Allah, on this day place me among those who seek forgiveness, place me among Your righteous and obedient servants, and place me among Your close friends, by Your kindness, O the most Merciful
