اللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنَ البُخْلِ، وَأَعُوذُبِكَ مِنَ الْجُبْنِ، وَأَعُوْذُ بِكَ مِنْ أَنْ أُرَدَّ إِلَى أَرْذَلِ الْعُمُرِ، وَأَعُوْذُ بِكَ مِنْ فِتْنَةِ الدُّنْيَا، وَأعُوذُبِكَ مِنْ عَذَابِ الْقَبْرِ

O Allāh, I take refuge in You from miserliness and cowardice, I take refuge in You lest I be returned to the worst of lives. And I take refuge in You from the trails and tribulations of this life and the punishment of the grave.
