وَالَّذينَ آمَنوا وَاتَّبَعَتهُم ذُرِّيَّتُهُم بِإيمانٍ أَلحَقنا بِهِم ذُرِّيَّتَهُم وَما أَلَتناهُم مِن عَمَلِهِم مِن شَيءٍ ۚ كُلُّ امرِئٍ بِما كَسَبَ رَهينٌ

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.
