4. Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa from Hariz from Zurarah who has narrated the following: “Abu Ja’far عليه السلام, has said, ‘You must not ignore Ghusl (bath) on Friday; it is a sunnah. You should use perfumes, dress up in you proper dress and you should complete your Ghusl (bath) before noontime. At Zawal (declining of the sun toward the west at noontime) rise up with calmness and dignity for prayer.’ He (the Imam) said, ‘Ghusl (bath) on Friday is obligatory.’”
