It was narrated from Abu Sa'eed Al-Khudri that: The Messenger of Allah passed by (the house of) one of the Ansar and sent word for him to come out. He came out with his head dripping and (the Prophet) said: "Perhaps we made you hurry?"He said: "O Messenger of Allah." He said, "If you are hurried (by someone) or obstructed (from orgasm) and do not ejaculate, then you do not have to take a bath, but you should perform ablution."

It was narrated from Abu Sa'eed Khudri that: He used to become sexually impure at night, then he would want to sleep. The Messenger of Allah told him to perform ablution and then go to sleep.
