اللَّهُمَّ اجْعَلْنِيْ مِنَ الَّذِيْنَ إِذَا أَحْسَنُوْا اسْتَبْشَرُوْا ، وَ إِذَا أَسَاءُوْا اسْتَغْفَرُوْا

Allahumaj ‘alna minal ladhina idha ahsanus tabasharti, wa idha asa’us-taghfaru  

O Allah!  make me among those who, when they commit an act of virtue, rejoice; and when they commit a mistake, seek forgiveness

 
[narrated by A’isha (radiAllahu anhu) – ibn Majah; #3810]
