Amatul Rahmân Omer:
It is not within your power (as far as natural feelings of love and devotion are concerned,) to maintain perfect balance between wives (and to treat them with equal justice) even though you be ever so eager; but do not incline with a total inclination (towards one so that you completely sever your relations with the other) so as to leave her like some thing suspended (as virtually deserted). And if you keep things right and guard against evil, then surely Allâh is Great Protector, Ever Merciful.
