Reference : Hisn al-Muslim 213

زَوَّدَكَ اللَّهُ التقْوى، 
وَغَفَـرَذَنْـبَكَ، 
وَيَسَّـرَ لَكَ الخَـيْرَ حَيْـثُما كُنْـت
Zawwadaka ‘llāhut-taqwā, 
wa ghafara dhanbak, 
wa yassara laka ‘l-khayra ḥaythu mā kunt.


May Allah give you piety as your provision, 
forgive your sins, 
and make goodness easy for you wherever you are.
