The Imam of the Sunnah and Hadeeth Ahmad bin Hanbal said:
«قبور أهل السنَّةِ من أهل الكبائر روضة، وقبور أهل البدعة من الزهاد حفرة. فساق أهل السنة أولياء، وزهاد أهل البدعة أعداء الله.»
❝The graves of the people of the Sunnah from the people of major sins are gardens and the graves of the people of Bida from the Zuhaad [Ascetics] are trenches. The evil ones from the people of Sunnah are Aawaliya and the Zuhaad [Ascetics] of the people of Bida are the enemies of Allaah.❞
[Tabaqaat al-Hanabila, (1/184) | Translated By Abbas Abu Yahya Miraath al-Anbiyya]
