welcome to our board, here is the Ayah responding to your question:
"And if you fear that you shall not be able to deal justly with the orphan girls, then marry (other) women of your choice, two or three, or four but if you fear that you shall not be able to deal justly (with them), then only one or (the captives and the slaves) that your right hands possess. That is nearer to prevent you from doing injustice."" (Quran 4:3)
