It is narrated from Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) that the people who used to give the verdict that the water of purification (ghusl) is used only after the discharge of semen, this was a concession. The Messenger of Allah (peace and blessings be upon him) had given this concession in the early days of Islam, but afterwards we were commanded to perform the full ritual bath (ghusl).
