Re: Shia And Sunni Muslims
Bottom line is that you were ignorant of this book and you without any investigation called it a Shia book, this shows how down you are interms of your anti-Shia sentiments that always lead you humilaited. “Al Bidayah Wal Nihayah” is the actual name of the book, not Tarikh Ibn Kathir, I used the urdu word “Tarikh” seeing that you are quite ignorant and may be this will make you realize your mistake.
Geoooooooo !!! First time ever in my life I have heard such condemntation of Ayesha’s act from a Sunni. I appritiate that you at least time time didnt show stubbornness. But for the benefit of readers, I would like to tell the consequences of doing Matam (which Ayesha did) according to Sunni school:
The Prophet said, “He who slaps the cheeks, tears the clothes and follows the tradition of the Days of Ignorance is not from us.”
Sahih Bukhari, Vol 2 Hadith 384
So she is no more from the nation, according to the fatwa of Prophet [s].
According to the above fatwa of Rasool Allah, (according to Sunni view), She no longer remains pious, for get about “very very pious” 
She is not even from the nation of Muslims according to the above hadith.
Wooooh !!! Thanx alot again. You know what, Sunnies specially Nawasib just die accepting the thing which you have just accepted. You know what, your acceptance that she went against Quraninc Injunction (33:33) also proves that shewas not pious (can a person who go against Quran be considered pious?). And by the way, the consequence of woman going against 33:33 also leads to the same place like it was in the tradition of Bukhari quoted abov, no longer from this nation rather from the previous nation of ignorance (Dau r Jaahilyah).
[Yusufali 33:33] And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance
Also as you said, she did wrong when she came out from her house and faught against Ali [as], let me also share you the result of the one who fights Ali [as]:
Prophet said: “Whoever obeys 'Ali, obeys me, whoever obeys me, obeys Allah, whoever disobeys 'Ali disobeys me, whoever disobeys me, disobeys Allah”
So I hope you do not consider the one who disobeys Allah [swt] and his prophet [s] to be pious. Because Quran consider such people from amonsgt disbelievers:
Surah Aal-e-Imran verse 32** Say, “Obey Allah and the Prophet, but if they turn back, then verily Allah does not love the disbelievers”**
Now, after you accepted that she did those sins, and i have enlighten you about the result/consequences of those sins, hence whatever good deeds she might have done in past becomes void. Thats what Quran tells us at various times that no matter how much good deeds a person might have done in past, but in big sin will destroy all of his previous efforts.
