What did the Prophet Muhammad (saw) advise a person who does not discharge during sexual intercourse with their wife?
 Narrated Ubai bin Ka`b:                     I asked Allah's Apostle about a man who engages in sexual intercourse with his wife but does not discharge. He replied, "He should wash the parts which comes in contact with the private parts of the woman, perform ablution and then pray." (Abu `Abdullah said, "Taking a bath is safer and is the last order.")
