The word(s) "unit" appears 15 time(s) in 15 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?

(12) But (later generations) cut off their affair (of unity), one from another: (yet) will they all return to Us.

(13) But people have cut off their affair (of unity), between them, into sects: each party rejoices in that which is with itself.

(14) Are your Unbelievers, (O Quraish), better than they? Or have ye an immunity in the Sacred Books?

(15) They will not fight you (even) together, except in fortified townships, or from behind walls. Strong is their fighting (spirit) amongst themselves: thou wouldst think they were united, but their hearts are divided: that is because they are a people devoid of wisdom.
