Method Of Ghusal
Bismillah hir-Rahman nir-Rahim
Narrated ‘Aisha radi allahu anha: Whenever the Prophet Sallallahu Alaihi Wasallam took a bath after Janaba He started by washing his hands and then performed ablution like that for the prayer.After that he would put his fingers in water and move the roots of his hair with them and then pour three handfuls of water over his head and then pour water all over his body.
Hazrat Aayesha radi allahu anah se rivayat hai ki Rasoollallahu Sallallahu Alaihi Wasallam jab janabat ka guhusal farmatey to pahley dono haath dhotey phir usi tarah wudhu kartey jaisa namaz ke liye Aap Sallallahu Alaihi Wasallam wudhu kiya karte they phir paani mein apni ungliyan dakhil farmatey aur unse baalon ki jadon (root of hair) ka khilal kartey phir apney haathon se 3 chullu sir par daltey phir tamam badan par paani baha detey.
Sahih Bukhari, wudhu ka Bayan (248)
