Translation:

16. But when He trieth him restricting his subsistence for him then saith he (in despair) "My Lord hath humiliated me!"

Notes (Tafseer)

6120. Subsistence, in both the literal and the figurative sense. Allah provides for all, but people complain if the provision is measured and restricted to their needs, circumstances, and antecedents, and does not come up to their desires or expectations, or is different from that given to people in quite different circumstances.
