from al-Husayn ibn al-Hasan ibn Aban, from al-Husayn ibn Sa'id, from Ya'qub ibn Yaqtin, from Imam Abu al-Hasan عليه السلام, who said: I asked Imam عليه السلام about ghusl for janabah - does it include wudu or not, according to what Jibra'il عليه السلام brought down? Imam عليه السلام said: "The junub (person in a state of major ritual impurity) performs ghusl, beginning by washing his hands up to the elbows before immersing them in the water. Then he washes off any impurities that are on his body, pours water over his head, over his face, and over his entire body. Once he has completed this, the ghusl is done, and he does not need to perform wudu."
