Arabic kerning groups

Does anyone came across info about Arabic kerning groups?

Thanks

They work just like kerning groups for other scripts. Anything in particular you need to know?

Thanks for the prompt response, I mean is there any common groups like latin where is MO and NO are one groups etc. , or is up to the designer, I know these could differ from font to another, but at least there should be common ones, right? Something like

بل بك با تا تل تك ثا ثا ثك يا يل يك

All should be one group, no need to kern each pair alone.

Right?

Most Arabic glyphs do not need kerning and thous don’t need groups.
