Obedience to our Messenger leads to Paradise – Importance of holding firm to the sunnah
Abu Huraira narrated that the Prophet (salaaAllahu alayhi wa sallam) said:
All of my ummah (people) will enter paradise except those who refuse.
They said: O messenger of Allah! Who would refuse?
He said: Those who obey me will enter paradise and those who disobey me has indeed refused.
