إِنَّا أَخْلَصْنَاهُم بِخَالِصَةٍ ذِكْرَى الدَّارِ
[38:46]
Surely We purified them by a pure quality, the keeping m mind of the (final) abode.
Verily We did choose them for a special (purpose)- proclaiming the Message of the Hereafter.
Lo! We purified them with a pure thought, remembrance of the Home (of the Hereafter).
