The Prophet (صلى الله عليه وسلم) said:

“There will not cease to be a group from my Ummah victorious upon the truth, not being harmed by those who oppose them until the command of Allaah comes about, and they are like that.” [Related by Muslim 6/52-53 and Abu Dawud 2/202]

Imaam Ahmad said:

“If this Taa’ifatul-Mansurah (Victorious and Aided Group) is not Ashaabul-Hadeeth, then I do not know who they are.” [Related by Ahmad (1/435) and also al-Hakim (2/318)]

al-Qadi Iyaad said:

“What Ahmad intended was Ahlus-Sunnah wal-Jamaah: those who hold the aqidah of Ahlul-Hadeeth.” [Imaam Nawawi, Sharh Saheeh Muslim 13/67]
