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

Al-Allaamah Saalih Al-Fawzaan [may Allah preserve him] stated: Ahlul Ahwaa [The people who are driven by their vain desires], such as the Mutazilah, the khawaarij, the Rawaafid, and others, are the ones responsible for causing the wars and discord. Fitnah (turmoil) only arises from them and is a result of them. Who was responsible for the assassination of Uthmaan? Who was behind the murder of Ali? Who were the ones that ignited turmoil among the Muslims thereafter? It was none other than these individuals driven by their desires. Who misled Al-Mamoon and those rulers who came after him to persecute Ahlus Sunnah, and ultimately led to the beating and imprisonment of their Imam – Ahmad Bin Hanbal? It was none else other than Ahlul Ahwaa! Who initiated the imprisonment of Shaikh Al-Islaam Ibn Taymiyyah until he died in prison? It was none else other than Ahlul Ahwaa! It is our responsibility to exercise caution towards these people, as their fitnah ultimately results in the fragmentation of Muslim unity, rebellion against Muslim leaders, and splitting within the Muslim community, leading to the emergence of divergent groups and parties. This stands in stark contrast to the concept of a united Ummah.
