﴿ إِلَّا ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ فَلَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍۢ ﴾

“excepting only such as attain to faith and do good works: and theirs shall be a reward unending!”

except those who believe and perform righteous deeds for they shall have an unfailing reward one unending — in a hadīth it is stated ‘When a believer reaches that stage of old age which prevents him from performing good deeds then what he used to do is recorded in his favour instead’.
