In The Name of Allaah, The Most Merciful, The Bestower of Mercy

Shaikh Shamsuddeen Al-Afghaanee As-Salafi [rahimahullaah] said: Ahlul Bidah are the ones who kindle trials and disorder.  They are a chaotic people and are deprived of safety and security.  They are a people of trials and disturbance as opposed to Ahlul Hadeeth Was-Sunan [i.e. those who steadfastly follow the ahaadeeth of the Prophet and his Sunnah]. Have they [i.e. the people of Sunnah] committed what the people of bidah and trials have committed?! The people of bidah trespass- alongside enmity and innovation- whilst Ahlus Sunnah respond and defend [the religion]. [Source: عداء الماتريدية للعقيدة السلفية 1/26-27]
