The word janabah refers to anyone who emits maniy (semen) or has intercourse; it is so called because he must avoid (ijtinab) prayer and other acts of worship until he has purified himself. The Prophet (blessings and peace of Allah be upon him) taught us in both word and deed how to do ghusl to cleanse ourselves from janabah, and the etiquette and Sunnahs of doing so. In this hadith, ‘A’ishah (may Allah be pleased with her) tells us that when the Prophet (blessings and peace of Allah be upon him) wanted to do ghusl to cleanse himself from janabah, he would prepare to do that and he would ask that a vessel the size of a milking pail be brought. This refers to a vessel big enough to hold the milk of a she-camel. Then he would take a handful of water and start with the right side of his head, then the left side, then he did that with both hands on his head. In other words, he would take some water in his hand the first time and wash his head, starting on the right side, then he would take another handful of water and wash his head, starting on the left side. That was because he liked to start on the right in all things. Then he would take water in both hands for the last time, and pour it all over his head from his two hands. This is the Sunnah of ghusl as is proven from the Prophet (blessings and peace of Allah be upon him). This hadith highlights how the wives of the Prophet (blessings and peace of Allah be upon him) were keen to describe the tiniest details of his life, so as to teach the ummah..
