Nawasib ideology must be destroyed, anyone that shows hatred towards Ali (ra) is a hypocrite.
Ibn Hajr on Ibn Taymiyyah:
“Others considered him a hypocrite [Munafiq] because of what he said about Ali… that he had been forsaken everywhere he went, had repeatedly tried to acquire the Khilafah and never attained it, fought out of lust for power rather than religion, and said that he loved authority while Uthman loved money. He would say that Abu Bakr had declared Islam in his old age, fully aware of what he said, while Ali had declared Islam as a boy, and the boy’s Islam is not considered sound upon his mere word… In sum he said ugly things such as these, and it was said against him that he was a hypocrite, in view of the Prophet’s (s) saying (to Ali): “Only a hypocrite would show you hatred”.
al-durar al-Kamina, Volume 1 page 153
The Prophet [saw] said: "Whoever's mawla I am, 'Ali is his mawla", and
Ali said: "The Prophet promised me, no one would love me except a believer and no one would hate me except a hypocrite."
You cant say, "Ali is not welcome here go to Iraq for that". Because if you consider the Prophet as your mawla, then so is Ali as well. Can you say the Prophet (saw) is not welcome here?
Did I said I deny the hadith.You should know that this is what the Prophet s.a.w in regards to Hassan r.a
So, Al-Hasan concluded a peace treaty with Muawiya. Al-Hasan (Al-Basri) said: I heard Abu Bakr saying, "I saw Allah's Messenger (ﷺ) on the pulpit and Al-Hasan bin `Ali was by his side. The Prophet (ﷺ) was looking once at the people and once at Al-Hasan bin `Ali saying, 'This son of mine is a Saiyid (i.e. a noble) and may Allah make peace between two big groups of Muslims through him."
وَلَقَدْ سَمِعْتُ أَبَا بَكْرَةَ يَقُولُ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى الْمِنْبَرِ وَالْحَسَنُ بْنُ عَلِيٍّ إِلَى جَنْبِهِ، وَهْوَ يُقْبِلُ عَلَى النَّاسِ مَرَّةً وَعَلَيْهِ أُخْرَى وَيَقُولُ " إِنَّ ابْنِي هَذَا سَيِّدٌ، وَلَعَلَّ اللَّهَ أَنْ يُصْلِحَ بِهِ بَيْنَ فِئَتَيْنِ عَظِيمَتَيْنِ مِنَ الْمُسْلِمِينَ ".
