[then,] O man - thou [that] hast, verily, been toiling towards thy Sustainer in painful toil - then shalt thou meet Him!

O thou man! Verily thou art ever toiling on towards thy Lord- painfully toiling,- but thou shalt meet Him.

Thou, verily, O man, art working toward thy Lord a work which thou wilt meet (in His presence).

O man, thou must strive a hard striving (to attain) to thy Lord, until thou meet Him.

O mankind, indeed you are laboring toward your Lord with [great] exertion and will meet it.
