"Mnakubali"

[Bassant_Gamal]

is the stem verb "bali" or "kubali" ?
and in negation will it be hamkubali or hambali?

[AGreatUserName]

It's kubali. The infinitive is kukubali. The fact that the stem begins with a "ku" is just coincidence. The negative is therefore hamkubali.

[JinaLangu1]

Shouldnt this be Unakubali, or am i missing something?

[hazzin13]

M- means you all or you (pl). It's in plural.
