The Messenger (salallāhu ‘alaihi wasallam) stated that this ummah (of Muslims) would divide into 73 sects – and these are the foundations of the sects, there are of course more sects than 73, but these 73 constitute the foundations of all of them. All of them will end up in the Fire except for one. So the seventy-third sect is upon that which the Messenger (salallāhu ‘alaihi wasallam) and his Companions (radiyallāhu ‘anhum) were upon – it is the sect saved (Arabic: nājiyah), saved from the Fire. For this reason, it is referred to as the Saved Sect (Firqat an-Nājiyah) and they are referred to as Ahlus-Sunnah wal-Jamā’ah. And all those besides them are the opposers, those threatened with the Fire.
Allah also says in the Qur'an:
وَإِن تُطِعْ أَكْثَرَ مَن فِي الْأَرْضِ يُضِلُّوكَ عَن سَبِيلِ اللَّهِ ۚ إِن يَتَّبِعُونَ إِلَّا الظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ
“And if you obey most of those upon the earth, they will mislead you from the path of Allah. They follow not except assumption, and they are not but falsifying.” (Al-An’ām: 116)
وَمَا أَكْثَرُ النَّاسِ وَلَوْ حَرَصْتَ بِمُؤْمِنِينَ
“And most of mankind will not believe even if you desire it eagerly.” (Yoosuf: 103)
وَمَا وَجَدْنَا لِأَكْثَرِهِم مِّنْ عَهْدٍ ۖ وَإِن وَجَدْنَا أَكْثَرَهُمْ لَفَاسِقِينَ
“And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient.” (Al-A’rāf: 102) So attention is not given to numbers, rather attention is given to those who are upon the truth even if they are small in number in a given time or place. So even if there is just one person, he can be considered the Jamā’ah.
It was said, “And who are they O Allah’s Messenger?” He responded, “That which I and my Companions are upon today.” So this is the correct path: whoever is upon that which the Messenger and his Companions were upon, he is the Jamā’ah.
