Hadith
Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Everyone from my nation will enter Paradise but those who refuse.” They said, “O Messenger of Allah, who will refuse?” The Prophet said, “Whoever obeys me enters Paradise, and whoever disobeys me has refused.”
عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ كُلُّ أُمَّتِي يَدْخُلُونَ الْجَنَّةَ إِلَّا مَنْ أَبَى قَالُوا يَا رَسُولَ اللَّهِ وَمَنْ يَأْبَى قَالَ مَنْ أَطَاعَنِي دَخَلَ الْجَنَّةَ وَمَنْ عَصَانِي فَقَدْ أَبَى
Sahih Al-Bukhari 7280
Ponder This Hadith
If the Prophet ﷺ clearly taught Namaz, fasting in Ramadan, Zakat, Hajj, and Tawhid – and obedience to him is what guarantees Paradise – what incentive remains to follow Ismaili Imams who teach an entirely different set of beliefs?
