You shall never be able to maintain real equality between wives, even though you are eager to. So, do not lean totally (towards one) and leave the other as suspended. If you act righteously and fear Allah, then, Allah is Most-Forgiving, Very-Merciful.
To Allah belongs what is in the heavens and what is in the earth. We have ordered those who were given the Book before you, and (ordered) you yourselves to fear Allah. If you disbelieve, then, surely to Allah belongs what is in the heavens and what is in the earth. Allah is All-Independent, Ever-Praised.
