وَالَّذِیْنَ اٰمَنُوْا وَاتَّبَعَتْهُمْ ذُرِّیَّتُهُمْ بِاِیْمَانٍ اَلْحَقْنَا بِهِمْ ذُرِّیَّتَهُمْ وَمَاۤ اَلَتْنٰهُمْ مِّنْ عَمَلِهِمْ مِّنْ شَیْءٍ كُلُّ امْرِىۢ بِمَا كَسَبَ رَهِیْنٌ ۟

Wallazeena aamanoo wattaba'at hum zurriyyatuhum bieemaanin alhaqnaa bihim zurriyyatahum wa maaa alatnaahum min 'amalihim min shai'; kullum ri'im bimaa kasaba raheen

“And those who believe and whose families follow them in Faith,- to them shall We join their families: Nor shall We deprive them (of the fruit) of aught of their works: (Yet) is each individual in pledge for his deeds.”
