A. Yusuf Ali:Translation:
Marry those among you who are single, 2988 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, 2989 and he
knoweth all things.

Muhammad Asad:Translation:
AND [you ought to] marry the single from among you 42 as well as such of your male and female slaves as are fit [for marriage]. 43 If they [whom you intend to marry] are poor, [let this not deter you;] God will grant them sufficiency out of His bounty - for God is infinite [in His mercy], all-knowing.
2988 The subject of sex ethics and manners brings us to the subject of marriage. "Single" (ayama, plural of Ayyim) here means any one not in the bond of wedlock, whether unmarried or lawfully divorced, or widowed. If we can, we must marry in our own circle, but if we have not the means, there is no harm if we choose from a lower circle, provided our choice is determined by virtue. Poverty in the other party does not matter if there is virtue and love. A happily married man has the best wealth in a virtuous wife, and his very happiness makes him a better potential earner of wealth. A slave becomes free by marriage.
2989 Cf. 10:57 Allah's mercy is for all: it is not confined to a class or grade of people.
