The Fifteenth Day Supplication
اَللّٰهُمَّ ارْزُقْنِي فِيْهِ طَاعَةَ الْخَاشِعِينَ
allahumma irzuqny fihi ta`ata alkhashi`ina
O Allah; on this day, (please) provide me with the obedience of those who are fearful of You;
وَ اشْرَحْ فِيْهِ صَدْرِي بِاِنَابَةِ الْمُخْبِتِينَ
washrah fihi sadry biinabati almukhbitina
And expand on this day my chest by granting me the turning of the submissive ones;
بِاَمَانِكَ يَا اَمَانَ الْخَائِفِينَ
bi-amanika ya amana alkha’ifina
Out of Your security; O the Grantor of security to the fearful ones.
