Marriage, slavery and freedom 24: 32- 33

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

But let them who find not [the means for] marriage abstain [from sexual relations] until Allah enriches them from His bounty. And those who seek a contract [for eventual emancipation] from among whom your right hands possess - then make a contract with them if you know there is within them goodness and give them from the wealth of Allah which He has given you. And do not compel your slave girls to prostitution, if they desire chastity, to seek [thereby] the temporary interests of worldly life. And if someone should compel them, then indeed, Allah is [to them], after their compulsion, Forgiving and Merciful.

What good deeds?

“If you fear becoming deluded and impressed by your deeds then remember whose pleasure you are seeking, and the joy (paradise) in which you want to be, and what punishment you fear. Whoever thinks about these things will diminish his deeds.” – Imam Shafi’i
