They were able to see with their own eyes what kind of man was the man who was ruling as a caliph of Islam, namely a man who love wine, racing dogs, gambling and a life of ease and luxury and shamelessly violated the honour of men, women and children alike. They returned to Medina in a state of profound unease: when they had told the people of the situation, a large group of men gathered and rose in a defiance of the murderous regime.
They expelled the governor of Yazid and his wicked and blood -thirsty agents from Medina. From this moment onwards, the ranks of those rebellions to the government of Yazid grew day by day; cries of 'death to Yazid and his corruption ' rang out all around Medina.
People spoke out for Islam from the platform (minbar) of the mosques, from the streets and squares, and whenever people would gather together, the courageously declared their opposition to Yazid, saying, "anyone who has killed the progeny of the Messenger of Allah, anyone who drink wine, does not fast or pray , is addicted to gambling and racing dogs, anyone who indulges in luxurious living, dancing and music, anyone who rules corruptly , thinking only of his won interests and never of the poor deprived people- such a man has no right to such position of power and authority over the Muslims; such a man must step down from his position and make away for another man.
We, Muslims of Medina, have pledged our allegiance to a man called Abdullah ibn Handhalah who is often called Ghasil al-Mala'ikah; we cannot bear to live under the tyranny and corruption of the debauched drunkard Yazid and his agents''. News of this rebellion of the Muslims of Medina reached Yazid's ears.
Yazid ordered his hated agents to go as soon as possible to the scene to the demonstrations : they were to quell the demonstrations and to stop the cry of those seeking truth and justice from reaching the ears of the rest of the rest of the Muslims .
The bloodthirsty Yazid had a man called Muslim ibn Uqbah (also known as Mushrif, the wanton spendthrift) brought before him, the latter had been a faithful friend of Yazid's father Mu'awiyah .He despatched Muslim ibn Uqbah at the head of a large army to crush the rebellious Muslim in Medina. After Marching for sometime, they came to a halt in the rocky area near Medina known as Harrah. The people of Medina set off towards them in order to defend their lives and honour.
