Ar-Room 30:28

He makes this comparison for you from your own lives: do you have among your slaves any partners who equally share with you whatever wealth we have given you[10], so you are fearing them as you fear one another[11]? This is how We make the verses clear for people who understand.

[10] Here Allah says that humans would not let their slaves be their partners in their wealth, how can they accept helpless humans as partners with Allah Who owns the whole universe in His dominion?!
[11] So you fear those slaves to share with you your wealth equally, similar to your fear of your free partners to share with you your wealth.

He presents to you an example from yourselves. Do you have among those whom your right hands possess [i.e., slaves] any partners in what We have provided for you so that you are equal therein [and] would fear them as your fear of one another [within a partnership]?[1144] Thus do We detail the verses for a people who use reason.

[1144] See footnote to 16:71.

28. He sets forth for you a parable from your ownselves: Do you have partners among those whom your right hands possess (i.e. your slaves) to share as equals in the wealth We have bestowed on you whom you fear as you fear each other? Thus do We explain the signs in detail to a people who have sense.[2]

[2] (V.30:28) That is: How do you join to Us partners of that which We created, while you for yourselves will not accept partners from your slaves?.

He coineth for you a similitude of yourselves. Have ye, from among those whom your right hands possess, partners in the wealth We have bestowed upon you, equal with you in respect thereof, so that ye fear them as ye fear each other (that ye ascribe unto Us partners out of that which We created)? Thus We display the revelations for people who have sense.
