عن عائشة قالت كان رسول الله صلى الله عليه وسلم إذا أراد أن يغتسل من الجنابة بدأ فغسل يديه قبل أن يدخلهما الإناء ثم غسل فرجه ويتوضأ وضوءه للصلاة ثم يشرب شعره الماء ثم يحثي على رأسه ثلاث حثيات (سنن الترمذي، الرقم: 104)
Hazrat Aaishah (radhiyallahu anha) reports that when Hazrat Rasulullah (sallallahu alaihi wasallam) would intend to perform fardh ghusl, he would commence by washing his mubaarak hands before submerging them in the utensil of water. Then, he would wash his private parts and perform wudhu, just as he would perform wudhu for salaah. Thereafter, he would wet his hair, after which he would pour three handfuls of water over his mubaarak head.”
2. Pour water over the right side of the body thrice from top to bottom and thereafter pour water over the left side of the body thrice from top to bottom. Ensure that water reaches every part of the body.
