If they are expelled, they will not leave with them, and if they are fought, they will not aid them. And [even] if they should aid them, they will surely turn their backs; then [thereafter] they will not be aided.

Tafsir of Verse 12
If those are expelled, they will not go forth with them, and if they are fought against, they will not help them. Even if they helped them, they would surely turn their backs, then they would not be helped.
If they are expelled, never will they go out with them; and if they are attacked (in fight), they will never help them; and if they do help them, they will turn their backs; so they will receive no help.
