361. Commandment – if you fear you will not deal justly, then marry only one

[4:4] And if you fear that you will not be fair in dealing with the orphans, then marry of women as may be agreeable to you, two, or three, or four; and if you fear you will not deal justly, then marry only one or what your right hands possess. That is the nearest way for you to avoid injustice.

[4:128] And they seek of thee the decision of the Law with regard to women. Say, Allah gives you His decision regarding them. And so does that which is recited to you in the Book concerning the orphan girls whom you give not what is prescribed for them and whom you desire to marry, and concerning the weak among children. And He enjoins you to observe equity towards the orphans. And whatever good you do, surely Allah knows it well.
