24:32
وَأَنكِحُوا۟ ٱلْأَيَـٰمَىٰ مِنكُمْ وَٱلصَّـٰلِحِينَ مِنْ عِبَادِكُمْ وَإِمَآئِكُمْ ۚ إِن يَكُونُوا۟ فُقَرَآءَ يُغْنِهِمُ ٱللَّهُ مِن فَضْلِهِۦ ۗ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ٣٢
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.
