Yazid's nomination was contested by the sons of a few prominent companions of Muhammad, including Husayn, son of the fourth caliph Ali, and Abd Allah ibn Zubayr, son of Zubayr ibn al-Awwam. Upon Muawiyah's death in 680 CE, Yazid demanded allegiance from Husayn and other dissidents. Husayn did not give allegiance and traveled to Mecca. The people of Kufa, an Iraqi garrison town and the center of Ali's caliphate, were averse to the Syria-based Umayyad caliphs and had a long-standing attachment to the house of Ali. They proposed Husayn overthrow the Umayyads. On Husayn's way to Kufa with a retinue of about 70 men, his caravan was intercepted by a 1,000-strong army of the caliph at some distance from Kufa.

Additional protection from lightning requires knowing the basics of earthing. Unexpected incidents such as high voltage or earth leakage may occur in our various installations. If they do, electrical appliances like TV, fridge, fan, line, etc. may get damaged. Basically, to protect the electrical equipment and its user in such situations, the current is sent from the metal or outer casing of the electrical equipment to the ground by a conductor. This process of sending electricity to the ground is called earthing. Earthing is often referred to as grounding by electrical engineers. Because through earthing it is possible to send electricity to the ground. If there is a leakage current in the electrical connection for any reason, earthing helps the leakage current to flow easily through the wire to the ground without causing any danger. আর্থিং - এর বর্ণনা ( Description of earthing ) 8 পৃথিবীর সমুদয় মাটির সঙ্গে কোনো কিছুর বৈদ্যুতিক সংযোগ স্থাপন করাকে আর্থিং ( Earthing ) বা আর্থ
