هُنَالِكَ تَبْلُوا۟ كُلُّ نَفْسٍۢ مَّآ أَسْلَفَتْ ۚ وَرُدُّوٓا۟ إِلَى ٱللَّهِ مَوْلَىٰهُمُ ٱلْحَقِّ ۖ وَضَلَّ عَنْهُم مَّا كَانُوا۟ يَفْتَرُونَ
There doth every soul experience that which it did aforetime, and they are returned unto Allah, their rightful Lord, and that which they used to invent hath failed them.
