Translation:

34. And He giveth you of all that ye ask for. But if ye count the favors of Allah never will ye be able to number them: verily man is given up to injustice and ingratitude.

Notes (Tafseer)

1910. Sincere and true prayer in faith is answered by Allah. Thus He gives us everything which a wise and benevolent Providence can give.

1911. I have tried to render the intensive forms of the Arabic by what I consider their near equivalent here: the phrase "given up to injustice and ingratitude" suggests habitual ignoring of just values and ingratitude for the innumerable gifts and favours which Allah has showered on mankind.
