رَبَّنَا فَاغْفِرْ لَنَا ذُنُوبَنَا وَكَفِّرْ عَنَّا سَيِّئَاتِنَا وَتَوَفَّنَا مَعَ الْأَبْرَارِ
Rabbana faghfir lana dhunubana wa kaffir 'anna sayyi'atina wa tawaffana ma'al-abrar
Our Lord, forgive us our sins and expiate our misdeeds, and cause us to die with the righteous.
Three requests in ascending order: forgive our sins (cover them), expiate our misdeeds (erase their consequences), and let us die among the righteous (the ultimate outcome). "Ma'al-abrar" — with the righteous — because how you die determines where you end up. The company you keep at death is the company you keep in the Hereafter.
