Sura al-Nūr 24:32

وَأَنكِحُوا۟ ٱلْأَيَٰمَىٰ مِنكُمْ وَٱلصَّٰلِحِينَ مِنْ عِبَادِكُمْ وَإِمَآئِكُمْ إِن يَكُونُوا۟ فُقَرَآءَ يُغْنِهِمُ ٱللَّـهُ مِن فَضْلِهِۦ وَٱللَّـهُ وَٰسِعٌ عَلِيمٌ

wa-ankiḥū al-ayāma minkum wa-l-ṣāliḥīna min ʿibādikum wa-imāʾikum in yakūnū fuqarāʾa yughnihimu allāhu min faḍlihi wallāhu wāsiʿun ʿalīmun

Marry those among you who are single, or the virtuous ones among yourselves, male or female: if they are in poverty, Allah will give them means out of His grace: for Allah encompasseth all, and he knoweth all things.
