An-Nur 24:32

وَأَنكِحُوا۟ ٱلْأَيَـٰمَىٰ مِنكُمْ وَٱلصَّـٰلِحِينَ مِنْ عِبَادِكُمْ وَإِمَآئِكُمْ ۚ إِن يَكُونُوا۟ فُقَرَآءَ يُغْنِهِمُ ٱللَّهُ مِن فَضْلِهِۦ ۗ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ

Wa-ankiḥū l-ayāmā minkum wal-ṣāliḥīna min ʿibādikum wa-imāikum in yakūnū fuqarāa yugh'nihimu l-lahu min faḍlihi wal-lahu wāsiʿun ʿalīmun

And marry the unmarried among you and the righteous among your male slaves and female slaves. If they should be poor, Allāh will enrich them from His bounty, and Allāh is all-Encompassing and Knowing.
