The title itself was first Given to Umar Ibn Khattab by the people, because Abu Bakr RA was called Khalifa tu Rasool Allah, when Umar RA took Charge calling him Khalifa tu Khalifa tu Rasool Allah would be awkward hence he was give this title of Amir ul Mumineen, As usual Shia who follow a cult of likes of Ibn Saba, have no intellectual capacity to either process Hadith nor study the right history and some how bring Ali RA into this as well.
Abu Bakr RA Al Sadiq the second greatest non Prophet man after Rasool Allah
Umar Ibn Khattab Al Farooq the third best non Prophet man after Rasool Allah and Abu Bakr RA
Uthman ibn Afaan Al Ghani the forth best non Prophet man after the three
Ali Ibn Abi Talib Al Asad, and Fifth best non Prophet man after all the above.
arguing with the Tehrani Cultist is no use, they are like brain dead zombies and indoctrinated to a degree that they can not even comprehend basics of Islam, on a pure Academic level majority of Shia of Today are either disbelievers or Musriks, they are as equal Muslims as Ahmadi, Ahmadi has their own Liar Mirza, while Shia cultists use Family of Prophet and elevate them to a level of demi Gods.
From Praying/Worshiping to horses to abusing Sahaba and Umhatul Mumineen, from beating the shit out of themselves to make fake Alm/Jhoolay and consider them to be holy, their scholars have used their mimber to express Direct shirk and yet they are well renounce Shia scholars and well respected, I used to be someone who wanted Shia/Sunni to have peace and never really did my own research in deep, but when i did All I can say is Astaghfirullah what they say and do in their majalis and called it Islam, and associate it with the family of Prophet, what a disgrace these People has brought to the family of Prophet, and to this date they are manipulating the dumb 12vers into innovating Bidat's in Islam and openly do Shirt in the name of Ali RA. If Ali/Hasan/Hussain/ RA to all were alive they would be the first to burn these cultists alive for their disgusting practices and language they use against the people even Ali RA respected till the day he was martyred. But what is the point? will they listen? will they question their Cult through rationale and reasoning ? No, they will just keep following what they are taught since they are young kids, a couple of points are given to these people to used against the Sunni's, such as Hadeeth Ghadir khum etc even that if you ask them to explain the context they will run like Shayateen Run from Ayatul Kursi lol
There will never ever be any Peace with Shia's for as long as they believe in their ideology of hate and Abuse, this divide will remain but Shiaism will never dominate the Sunnah because as they say, Jhoot ke pair nai hote and this cult is literally based on a lie/deception and fabrication.
So is sunnism and anyother ism. Allah Swt encourages ciritcal thinking but not sectarianism.. We can have genuine difference of opinion but still be part the of herd. The moment you adopt a label you get deprived of Devine protection instantly
There is no Sunnism, Shia and Sunni not just have difference of opinion, they are two separate Religion with separate Ideologies, I can bet my life that There will be no divine Protection for those who in their Majalis abuse Sahaba and Wives of Prophet.
