Ref. No. 41/1087
In the name of Allah the most Gracious the most merciful
The answer to your question is as follows:
The below mentioned narration relates that only one sect of ummah will enter paradise.
It is narrated in many books of hadith that the Prophet of Allah (saws) said: ‘The Bani Israel was divided into 72 sects; my Ummah will be divided into 73 sects and all of them will go to Hell, except one. The Sahaba (Companions) said: ” O’ Messenger of Allah! Which is that ‘one’ sect likely to receive salvation?” The Beloved of Allah (saws) replied, the one that is Me and my companions.
(ان بنی اسرائیل تفرقت علی ثنتین وسبعین ملۃ وتفترق امتی علی ثلاث وسبعین ملۃ کلھم فی النار الا ملۃ واحدۃ قالوا من ھی یا رسول اللہ ﷺ قال ما انا علیہ واصحابی۔ (رواہ الترمذی –مشکوۃ)۔
