And Allah created you; then He will take you in death. And (16:70)

Almuntakhab Fi Tafsir Alquran Alkarim

And Allah is He Who brought you people into being and caused you to exist. Then He disembodies your souls and deprives you of animate existence, and among you is he who is carried through the stealing steps of age to advanced life that he loses the wits once about him and he loses remembrance of the knowledge he formerly mastered and he becomes the abject heir of an illustrious name

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

(16:70) And consider this: Allah created you: then He causes your death; *60 and some one from among you is carried on to abject old age so that after knowing all he could, he may no longer have any knowledge of it. *61 The fact is that Allah alone is All-Knowing, All-Powerful.

And Allah created you; then He will take you in death. And meaning

*60) It is to emphasize this: Allah not only provides you with the necessities and good things of life (as stated in the preceding verses), but also has full power over your life and death. None else has any power to give lift or cause death.
*61) This fact has been mentioned to bring home to the disbelievers and the mushriks that knowledge, which gives superiority to man over all creatures on this Earth, has been given by Allah, as if to say, "You yourselves have seen that when a man, who once possessed much knowledge, becomes very old, he is reduced to a mere lump of flesh. Then that man who once taught knowledge to others loses all his senses and cannot look even after his own self".
 

And Allah created you; then He will take you in death. And meaning in Urdu

اور دیکھو، اللہ نے تم کو پیدا کیا، پھر وہ تم کو موت دیتا ہے، اور تم میں سے کوئی بد ترین عمر کو پہنچا دیا جاتا ہے تاکہ سب کچھ جاننے کے بعد پھر کچھ نہ جانے حق یہ ہے کہ اللہ ہی علم میں بھی کامل ہے اور قدرت میں بھی
