وَإِنْ خِفْتُمْ أَلَّا تُقْسِطُوا فِى ٱلْيَتَـٰمَىٰ فَٱنكِحُوا مَا طَابَ لَكُم مِّنَ ٱلنِّسَآءِ مَثْنَىٰ وَثُلَـٰثَ وَرُبَـٰعَ ۖ فَإِنْ خِفْتُمْ أَلَّا تَعْدِلُوا فَوَٰحِدَةً أَوْ مَا مَلَكَتْ أَيْمَـٰنُكُمْ ۚ ذَٰلِكَ أَدْنَىٰٓ أَلَّا تَعُولُوا

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].
