Ahmed Raza Khan: Mohammed Aqib Qadri:
And you will never be able to deal equally between women however much you may desire - therefore do not be totally inclined towards one leaving the other in uncertainty; and if you do good and practice piety, then (know that) Allah is Oft Forgiving, Most Merciful.

Yusuf Ali:
Ye are never able to be fair and just as between women, even if it is your ardent desire: But turn not away (from a woman) altogether, so as to leave her (as it were) hanging (in the air). If ye come to a friendly understanding, and practise self-restraint, Allah is Oft-forgiving, Most Merciful.

Pickthal:
Ye will not be able to deal equally between (your) wives, however much ye wish (to do so). But turn not altogether away (from one), leaving her as in suspense. If ye do good and keep from evil, lo! Allah is ever Forgiving, Merciful.
