Night and day!
It is part of Shia religion to abuse and revile the Sahabah (RA).
It is part of Sunni Aqeedah to honour and respect the Sahabah (RA).
Then it is part of our Aqeedah that we do not curse or invoke curse of Allah Ta'ala on people of Ahlus-Sunnah specifically but we condemn their actions. This Aqeedah is manifested in the direct Hadeeth of Nabi (Sallallaho Alaihe Wassallam).
- The evidence quoted by you to CURSE Maulana Salman Nadwi (HA) is "Munkar Hadeeth"
- The evidence being followed by me not to CURSE Maulana Salman Nadwi (HA) is "Authentic Hadeeth"
- Thus, I do not want to invoke "Curse of Allah" upon him
I am under no obligation in Islam or by Allah to DISOBEY Authentic Hadeeth to invoke a Curse. I am expressly forbidden in Islam curse specific Sunni Ulama on errors and mistakes.
You know it, you understand it.
You know that you are wrong, you understand that you are wrong.
But you will keep on arguing because your ego will not let you admit your error even when your understanding violently collides with the Aqeedah of Islam and principles of Qur'aan and Sunnah. A "Muslim" by nature will back down when their understanding collides with the Qu'raan and Sunnah, you usually don't.
Your ego won't let you.
The issue here isn't cursing an act but cursing a specific person who may or may not have retracted what he said.
