Translation:

73. (With the result) that Allah has to punish the Hypocrites men and women and the Unbelievers men and women and Allah turns in Mercy to the Believers men and women: for Allah is Oft-Forgiving Most Merciful.

Notes (Tafseer)

3783. Man's generic Covenant, which flowed from his exercising the option given him, choosing Will, Forbearance, Love, and Mercy, made it necessary that breach of it should carry its own punishment. Breach of it is here classed under two heads: those who betray their Trust act either as Hypocrites or as Unbelievers. Hypocrites are those who profess Faith but bring not forth the fruits of Faith. Unbelievers are those who openly defy Faith, and from whom therefore no fruits of Faith are to be expected.

3784. Those who remain firm to their Faith and their Covenant (see notes 3781-82) will receive the aid of Allah's Grace; their faults and weaknesses will be cured; and they will be made worthy of their exalted Destiny. For Allah is Oft-Forgiving and Most Merciful. So ends a Sura which deals with the greatest complications and misunderstandings in our throbbing life here below, and points upwards to the Great Achievement, the highest Salvation.
