Musannaf Ibn Abi Shaybah 690 — Ghusl for janabah

Sayyidah Aishah (may Allah be pleased with her) said: the Prophet (peace and blessings be upon him) took the bath for janabah in this way: first he washed both palms three times, then performed ablution as for prayer. Then he put his hand into his hair and passed his fingers through it in such a way that the water reached the skin. Then he poured water over his head three times, then poured water over his body.
