Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) passed by an Ansari man. The Prophet (peace and blessings be upon him) sent a message to him. When he came out, water drops (from bathing) were dripping from his head. The Prophet (peace and blessings be upon him) said to him: "Perhaps we made you hurry." He replied: "Yes, O Messenger of Allah!" The Prophet (peace and blessings be upon him) said: "When you are made to hurry or there is no ejaculation, then there is no ghusl (ritual bath) required upon you. In such a case, perform wudu (ablution)."
