Whoever guides someone to good has a reward like the one who does it.
Sahih Muslim · 1893
اللَّهُمَّ اجْعَلْ خَيْرَ عَمَلِي آخِرَهُ، وَخَيْرَ أَيَّامِي يَوْمَ أَلْقَاكَ، وَاجْعَلْنِي مِمَّنْ يُبَشَّرُ بِرِضْوَانِكَ وَجَنَّتِكَ.
Allāhumma ijʿal khayra ʿamalī ākhirahu, wa khayra ayyāmī yawma alqāka, wa ijʿalnī mimman yubashsharu biriḍwānika wa jannatika
O Allah, make my best deed my last, my best day the day I meet You, and make me among those given glad tidings of Your pleasure and Paradise.
Hereafter
Allāhumma ijʿal khayra ʿamalī ākhirahu, wa khayra ayyāmī yawma alqāka, wa ijʿalnī mimman yubashsharu biriḍwānika wa jannatika
A complete and beautiful du’a for a righteous end and glad tidings of Paradise.
