﴿ إِذْ تَبَرَّأَ ٱلَّذِينَ ٱتُّبِعُوا۟ مِنَ ٱلَّذِينَ ٱتَّبَعُوا۟ وَرَأَوُا۟ ٱلْعَذَابَ وَتَقَطَّعَتْ بِهِمُ ٱلْأَسْبَابُ ﴾

“[On that Day] it will come to pass that those who had been [falsely] adored shall disown their followers, and the latter shall see the suffering [that awaits them], with all their hopes cut to pieces!”

When idh here substitutes for the previous idh those who were followed that is the leaders disown their followers that is to say when they have denied misleading them the latter and they have seen the chastisement and the cords the bonds of affection and kinship that were between them on earth are cut away before them from them taqatta‘at ‘cut away’ is a supplement to tabarra’a ‘disown’.
