“Their grudge is against every believer,
and their evil deeds shall always be leveled against every Muslim.
It as an animosity directed at the very duality of faith, or indeed against faith itself.
This has always been the case with the enemies of faith, in all periods of history. Thus said the sorcerers to Pharaoh when he threatened them with torture, vengeance and a woeful doom:
“You want to take vengeance on us because we have believed in the signs of our Lord when they were shown to us.” [7:126]
The same was said by the Prophet (sallallaahu ‘alayhi wa sallam), on Allaah’s instructions, to the people of earlier revelations who opposed him:
“Say, O People of the Book, do you find fault with us for any reason other than we believe in Allaah alone.” [5:59]
In reference to the People of the Pit, who in former times burned the believers with their women and children, Allaah says:
“They took vengeance on them for no reason other than that they believed in Allaah, the Almighty, the Praised One.” [85:8]
Faith is then the cause of all their hatred for the believers.
Hence, their ill-will and atrocities are directed against every believer.
“They respect neither agreement nor obligation of honor with regard to any believer. Those indeed are the transgressors.” [9:10]
It is their nature that they are aggressors. Their aggression begins with their hatred of the Divine faith and their rejection of its message.
It is their aggression that leads them to stand in opposition to faith and adopt a hostile attitude to the believers…”
