And he to whom We grant long life We reverse in creation; (36:68)

Almuntakhab Fi Tafsir Alquran Alkarim

Do they not ponder that he whom We carry through the stealing steps of age to advanced life, We cause to relapse into a degenerate and degraded state of mind, activity, knowledge, strength and status and make him lose the qualities and attributes he once possessed. Do they not deviate into sense and contemplate this fact

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(36:68) Whomsoever We grant a long life, We reverse him in his constitution. *57 Do they still not understand?

And he to whom We grant long life We reverse in creation; meaning

*57) "Reverse him in nature," means that in old age Allah turns him back to the state of childhood. He becomes unable to stand and walk without the help and support of others; he is fed by others; he urinates and defecates in bed; talks childishly and is laughed at by others. In short, towards the end of life he returns to the same state of weakness with which he had started lift in this world."
 

And he to whom We grant long life We reverse in creation; meaning in Urdu

جس شخص کو ہم لمبی عمر دیتے ہیں اس کی ساخت کو ہم الٹ ہی دیتے ہیں، کیا (یہ حالات دیکھ کر) انہیں عقل نہیں آتی؟
