تفيّظوا
Root: فيظ
Full Definition
تفيّظوا
They constrained themselves to vomit forth their souls. [But in one copy of the S, I find يُفِيظُوا أَنْفُسَهُمْ, expl. as meaning They cause to vomit forth their souls; which suggests that the right reading may perhaps be يُفِيظُوا: or it may be يَفِيظُوا, from فَاظَ نَفْسَهُ.]
