In Shia Islam, Sunnah is followed.
Really? Is that why you also have annual commemorations of Imam Hassan (ra) making peace with Muawiya? Oh wait, you don't have such a day.
Because it showed that on assuming power Yazeed acted contrary to the commandments of ALLAH (SWT) - thus justifying that he is not to be given bayah as he is not eligible to become Ruler of Muslims.
I'm fine with that.
Bayah of Imam Hussain (a.s) would had legitimize the rule of Yazeed even if others had not given bayah before Imam (a.s).
....and bayah of Imam Hassan (ra) did not legitimize the rule of Muawiya, a "hypocrite and nasibi" (according to you)? Why was legitimizing the rule of a kafir (Yazeed) worse than legitimizing the rule of a "hypocrite and nasibi" (Muawiya)?
Imam Hassan (a.s) never accepted "ignominy" and Imam (a.s) making peace treaty was an act which was praised by the Prophet (s.a.w.w) himself
The Prophet (saw) praised Imam Hassan (ra) as per the authentic sunnah not as per your madhhab. Is there praise for Imam Hassan (ra) within your madhhab for handing over his "Divinely Ordained Leadership" to a "hypocrite and nasibi"? Does it rationally make sense for an Imam (ra) to forsake his "Divinely Ordained" responsibilities and trust a "hypocrite and nasibi" with it?
As I alluded to in my opening post, without authentic Sunnah, you're lost. You can either accept that Imam Hassan (ra) chose "ignominy" while Imam Hussain (ra) fought valiantly OR you have to praise Imam Hassan (ra) and reprimand Imam Hussain (ra) for disregarding his older brother's (ra) legacy and going about things his own way (naudhubillah).
"Divinely Ordained Leadership" is not something which could be handed over to someone by people. It is Only ALLAH (SWT) who chooses and gives. Can Nabi Ibrahim (a.s) give his Nubuwwah to Nimrod (l.a) or can Nabi Musa (a.s) give his Nubuwwah to Firawn (l.a)? It is Only ALLAH (SWT) who gives Nubuwwah, Risalah and Imamah to whomsoever HE (SWT) Wills.
You cannot bring Prophethood in a conversation to support Imamah. The former is established by Qur'an and Sunnah; the latter is alien to both the Qur'an and Sunnah. It is a made up concept and its' rules are too. As far as actions are concerned, Imam Hassan (ra) did concede power to Muawiya.
Imam Hassan (a.s) did not hand his Imamat to Muawiya but he (a.s) only handed the ruler-ship to Muawiya in order to make peace between Muslims and save Islam from internal war and conflict which would had weakened the religion.
Again, that is the authentic Sunnah, not your narrative; you keep saying it because I subscribe to authentic Sunnah. As for as you are concerned, the action of Imam Hassan (ra) flies in the face of everything your madhhab preaches and is quite discomforting for Shias. Don't you find it problematic that when Saqifah happened, Shias say Imam Ali (ra) remained silent due to lack of power (although he had control over atoms) but when Imam Hassan (ra) had power, he gave it up. Then, Imam Hussain (ra), with only 72 people, stood up to Yazeed.
Imam Hassan (a.s) nor Imam Ali (a.s) nor Imam Hussain (a.s) had any interest in ruler-ship neither did they seek ruler-ship. Seekers of ruler-ship are disliked by ALLAH (SWT) and HIS (SWT) Messenger (s.a.w.w) and they (seekers) would be Judged by ALLAH (SWT) Harshly.
Imam Ali (ra) did not have any interest in rulership? Then what was the Sermon of Shiqshiqiyah about? Playing harps and singing hymns?
I think that particular reason was not strong enough for Abdullah ibn Umar as he not only gave bayah to Yazeed but cited Prophet's (s.a.w.w) hadith (of betrayer on the day of Judgement) to those people who had dethroned Yazeed and seperated himself from those people who dethroned Yazeed.
Raza brought up the same point to brother Adnan Rashid and got schooled. Abdullah ibn Umar (ra) was only advising a group of people to not withdraw their bayah after they had already pledged allegiance to Yazeed. Please read the entire narration and you'll find the reason why Abdullah ibn Umar (ra) suggested them not to withdraw their bayah or go against Yazeed.
And bear in mind that this was the same Abdullah Ibn Umar (ra) who rode to meet Imam Hussain (ra) and begged him not to go to Kufa; he even cried while beseeching Imam Hussain (ra) to change his mind.
Imam Hassan (a.s) making peace treaty was praised by Prophet (s.a.w.w) himself which shows that Imam Hassan (a.s) was upon Haq.
Is it praiseworthy, according to you, to deliver your "Divinely Ordained Leadership" into the hands of a "hypocite and nasibi"? You keep running away from this point while equating it to prophethood when it has nothing to do with it.
