COMMENTARY on 90:4
A. Yusuf Ali:

Translation:
Verily We have created man into toil and struggle. 6133
Commentary:

6133  Cf. "Man is born unto troubles as the sparks fly upward" (Job, 5:7); "For all his days are sorrows, and his travail grief (Ecclesiastes, 2:23). Man's life is full of sorrow and vexation; but our text has a different shade of meaning: man is born to strive and struggle; and if he suffers from hardships, he must exercise patience, for Allah will make his way smooth for him (65:7; 94:5-6). On the other hand no man should boast of worldly goods or worldly prosperity (see verses 5-7 below).

 

Muhammad Asad:

Translation:
Verily, We have created man into [a life of] pain, toil and trial. 3
Commentary:
3  The term kabad, comprising the concepts of "pain", "distress", "hardship", "toil", "trial"', etc., can be rendered only by a compound expression like the one above.
