Dua, seeking best, by Abu Bakr Siddiq (RA)

اللَّهُمَّ اجْعَلْ خَيْرَ زَمَانِيْ آخِرَهُ، وَخَيْرَ عَمَلِيْ خَوَاتِمَهُ، وَخَيْرَ أَيَّامِيْ يِوْمَ أَلقَاكَ

“O Allah, let the best of my lifetime be its ending, and my best deed be that which I seal [my life with], and the best of my days the day I meet You.”
