As-salamu alaykum wa rahmatullahi wa barakatuh,
There is a website where a person calling himself (Abu Nu'aym) writes. It seems he is practically dying of rage against Hizb ut-Tahrir and its members. He hurls foul insults and abuse at the Hizb, its leadership, its youth, its media spokesmen, and its forums—abuse so excessive that no one possessing even a shred of intellect or decency would utter it. He particularly singles out the city of Al-Khalil (Hebron) and its people with much of this abuse and slander because it has produced many of the Hizb's youth...
O brothers, I prefer not to respond to him, so that our tongues, which are moist with the remembrance of Allah, remain pure and untainted by the filth of that individual known as (Abu Nu'aym). Rather, we entrust him to Allah, the All-Strong, the All-Mighty, the Avenger, the Compeller, Who defends those who believe. I want all of you to perform qunut (supplication) against him and those behind him, whether they are states or movements, for a period of three days. Allah is the Helper, and upon Him alone is our reliance.
Ata Bin Khalil Abu Al-Rashtah Ameer of Hizb ut-Tahrir
