as a Sunni Muslim I answer that question like this: Ali was the fourth khalifah after Abu Bakr, Umar, Uthman he was murdered by ibn Muljim after his death some Muslims vote for his son Hussein to be Khalifah and other vote for Mo'aweyah ibn Abi-Sufyan and there were battles between the two sides eventually, Hussein gave in the Khilafah to protect and save people from killing each other
In the Qur'an, the name is simply "Zaid", with no additional names.We know from sources like Tabari that his full name was Zaid al-Habib ibn Harithah ibn Sharahil ibn Abduluzza ibn Imri al-Qays ibn Amir ibn Al-Numan ibn Amir ibn Abdwalid ibn Awf ibn Kinana ibn Awf ibn Uzra ibn Zaidallat ibn Rufayda ibn Thawt ibn Kalb ibn Wabara ibn Taghlib ibn Talwan ibn Irmram ibn Al-Haf ibn Quda'a ibn Malik ibn Amr ibn Murrah ibn Malik ibn Himayr ibn Saba ibn Yashjub ibn Yarab ibn Qaltan.Al-Habib ("the beloved") was a byname; Uzra was his clan; Kalb was his tribe proper; Taghlib was his super-tribe; Himayr was the general group of tribes in the area.So are you surprised that the Qur'an simply calls him "Zaid"?
