And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hands possess [i.e., slaves]. That is more suitable that you may not incline [to injustice].
— Saheeh International
If you fear that you will not deal fairly with orphan girls, you may marry whichever [other] women seem good to you, two, three, or four. If you fear that you cannot be equitable [to them], then marry only one, or your slave(s): that is more likely to make you avoid bias.
— M. A. S. Abdel Haleem
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 slaves) that your right hands possess. That is nearer to prevent you from doing injustice.
— Muhammad Muhsin Khan & Muhammad Taqi-ud-Din al-Hilali
