His eminence, al-Allaamah, Shaykh ‘Abdul ‘Azeez ibn Baaz, may Allaah Ta’ala have mercy upon him, was asked: May Allaah grant you much good. In the hadeeth of the Prophet (صلى الله عليه وسلم) regarding the breaking up of the nations, he (صلى الله عليه وسلم) said: “My Ummah (nation) will break up in to seventy three sects [all of them in the fire] except one". So the Jama’at at-Tableegh, with what they have from the aspects of shirk and innovations and the Ikhwaanul Muslimeen, with what they have from aspects of hizbiyyah (partisanship), who revolt against the authority of the Muslim rulers and who disobey them, do these two groups enter into the destroyed sects?
So he - may Allaah forgive him and bestow upon him the vastness of His mercy - answered by saying: They enter in to the seventy two (destroyed sects). Whosoever goes against the ‘aqeedah of Ahlus Sunnah enters in to the seventy two (destroyed sects).
The meaning of his (صلى الله عليه وسلم) statement: “my Ummah (nation)", is the Ummah of Ijaabah, meaning the nation that responded; the ones who responded (to his way) and showed their allegience to him. And the meaning of seventy three sects: The victorious sect, the saved (sect), is the one that adhered to him and were upright upon their religion and the seventy two sects includes the disbelievers, the sinners, and the innovators.
Then the questioner said: You mean, that these two groups (Jama’at at-Tableegh and al-Ikhwaanul Muslimeen) are from the seventy two (destroyed sects)?
The Shaykh answered: Yes, they are from amongst the seventy two, the likes of the Murji’ah and other than them. The Murji’ah and the Khawaarij, some of the people of knowledge are of the opinion that the Khawaarij are disbelievers outside (the fold of Islaam), but generally are included amongst the seventy two.
