Background of Quraysh Tribe

While Searching for Imam Hussain (A.S) .. I came across history of Quaysh The tribe of Arabia.
Also I wanted to share with you guys some more, heart breaking things, I want to correct myself so feel free to share with me what information you got.

There was a Tribe named Quresh back then 1500 years ago.

That Quresh Tribe had two clans
you can say branches.

1. Hashimi Clan <= that's where Imam Hussain (A.S) Belonged

2. Ummayad Clan <========= that's where Yazeed belonged

People Call them Qureshi, or Hashimi after their Tribes names, in Muslim World

So after the fight was over between Imam Hussain (A.S) and Yazeed .. I really wanted to knew what happened to Yazeed, where did he go, or what did He do..
Here is what I found, its hurting, I thought It was over, he got what he needed, got ruling, Murdered Imam .. that's what he needed right? No!! that's not what He needed, He was against Islam itself not just against Imam Hussain (A.S) ... I tell you why
During his 3 years Ruling period that's what he did

1. after karbala, Murdering people. he took the woman which were left with him :'(

2. he murdered thousands of men and women in Madina, 3 days no prayer call from Masjid e Nabwi, no prayers were performed,

This is the most hurting part :'(

3. He attacked Makkah, burnt Kaaba, .. and said, Prophecy of Hashim was just a drama, there were no angels, and there were no messages from God, It was a game setup by Hashimis.

(He was ignorant, just like other Kaafirs(People Who disagree with Islam), He also did Kufr(disagreement with Islam))

You can search for 3 years of Yazeed ruling, and find reference books, and correct me if I am wrong.
Clearly: He was Khariji, I know now, why Him, and his Followers are called Kharijis(People Out of Islam), .. that's because they don't belong to Islam at all. They are out of Islam. They didn't believed in Islam ..

If these facts Establish, I can clearly infer this,
Yazeed was not after Caliphate(Becoming a Ruler), He was not After Imam Hussain (A.S) but He was after "Islam" itself ..
His Target was Islam ...

( By the way this information, I inferred by reading some articles searching google they also had book references, I didn't went into those books, So don't consider this information as facts. It may or may not be correct, I am not a History Expert, that's what I read and that's what I inferred )

Note:

You should study about History, it teaches you alot about you, and about others
and possibly you can learn from it. and get to know people more.
Whenever you find something that is confusing, or its hurting you..
you better ask someone for help and solve your misconceptions

Islam is Still here, and It will be here .. no matter how many Yazeeds come out, and try to destroy it
