Qur'an 52:21

وَٱلَّذِينَ ءَامَنُوا۟ وَٱتَّبَعَتْهُمْ ذُرِّيَّتُهُم بِإِيمَـٰنٍ أَلْحَقْنَا بِهِمْ ذُرِّيَّتَهُمْ وَمَآ أَلَتْنَـٰهُم مِّنْ عَمَلِهِم مِّن شَىْءٍ ۚ كُلُّ ٱمْرِئٍۭ بِمَا كَسَبَ رَهِينٌ

“And those who believed and whose descendants followed them in faith - We will join with them their descendants, and We will not deprive them of anything of their deeds. Every person, for what he earned, is retained.”
