seems like an issue with liga ... i'm not sure if that's a context problem

\definefontfeature % might move
   [somearabic]
   [mode=node,language=dflt,script=arab,
    init=yes,medi=yes,fina=yes,isol=yes,
%  liga=yes,
    calt=yes,
    mark=yes,
    mkmk=yes,
    curs=yes]

\definefont[amiri][file:uthmantn1ver10.ttf*somearabic at 32pt]

\setupalign[r2l]

\starttext

     \amiri نَسْتَعِينُ وَلَا الضَّالِّينَ

\stoptext
