Yazid Ibn Muawiyah

How on earth can these traditions apply for a beast like Yazid Ibn Muawiyah, who Fought against and mercilessly martyred Imam Husain (A.S), his family and friends Was a transgressor who committed sins publicly and announced his disbelief freely becoming a part of the renowned poems of Ibn al-Zabari, which he (Yazid) recited in joy when the severed head of Imam Husain (A.S) was brought to him.
He was the one who ordered Muslim Ibn Aqabah to kill and plunder the people of Madinah on three occasions. During these attacks, he killed a number of companions and the city of Madinah was totally ransacked. It was during these attacks that more than 1000 Muslim virgins were raped and whenever a Muslim from Madinah offered his daughter in marriage, he did not guarantee her virginity saying, perhaps, she has lost her virginity during the Tragedy of Haraa. It is said that four thousand illegitimate children were born after this incident. Muslim, in his Saheeh, reports that the Messenger of Allah (P.B.U.H&H.P) warned, whoever frightens the people of Madinah, Allah will frighten him and upon him is the curse of Allah, the angels and all mankind. [Murooj al-Zahab, vol. 3, pg. 69.]
Waaqedi narrates on the authority of Abdullah Ibn Hanzalah, By Allah! We did not visit Yazid but that we feared a stone falling on our heads from the sky (as a divine punishment) because he was a man who married his mothers, daughters and sisters, drank wine, did not pray [Taarikh al-Khulafaa, pg. 209] and he is the one who had ordered the attack on the Holy Kaaba.
Suyuti and others report on the authority of Nawfil Ibn Abi al-Furaat, I was with Umar Ibn Abd al-Aziz, when a person while mentioning Yazid, said, the chief of the faithful, Yazid Ibn Muawiyyah. On hearing this, Umar Ibn Abd al-Aziz (became angry) and asked, you call Yazid as Ameerul Momineen? And ordered that he be whipped 20 lashes. [Al-Sawaaeq al-Mohreqah, pg. 219, printed at Cairo; Taarikh al-Khulafaa, pg. 209, printed at Egypt.]
It is mentioned in Al-Sawaaeq that it was said to Saad Ibn Hassan, The Bani Umayyad claim that the caliphate is among them. He retorted, the sons of the blue-eyed (referring to Hind the wife of Abu Sufiyan) are lying. They are mere kings; nay, the worst of kings.
