Quran 52:21 from Surah At-Tur on Divine Marvels.
وَٱلَّذِينَ ءَامَنُواْ وَٱتَّبَعَتۡهُمۡ ذُرِّيَّتُهُم بِإِيمَٰنٍ أَلۡحَقۡنَا بِهِمۡ ذُرِّيَّتَهُمۡ وَمَآ أَلَتۡنَٰهُم مِّنۡ عَمَلِهِم مِّن شَيۡءٖۚ كُلُّ ٱمۡرِيِٕۭ بِمَا كَسَبَ رَهِينٞ
English translation: And those who believed and followed them their offspring in faith We will join with them their offspring and not We will deprive them of their deeds (in) any thing Every person for what he earned (is) pledged
Transliteration: wa-alladhina amanu wa-ittaba'athum dhurriyyatuhum biimanin alhaqna bihim dhurriyyatahum wama alatnahum min amalihim min shayin kullu im'ri-in bima kasaba rahinun
