One of the highest ranks in hereafter is the envy of the martyrs and Mujahedeen for the position of a righteous servant which this great honor has been given to Hazrat Abbas (AS).
" إِنَّ للعبّاس عندَاللهِ مَنزِلَةً یَغبِطُهُ بِها جَمیعُ الشُهداء یَومَ القِیامَة"
"indeed, Hazrat Abbas (AS) has a position and status before Allah Almighty that All the martyrs begrudge him on the day of resurrection".
