It is narrated from Hazrat Miqdad bin Aswad (may Allah be pleased with him) that once Hazrat Ali (may Allah be pleased with him) said to me: Ask the Prophet Muhammad (peace and blessings be upon him) about the ruling for a person who "plays" with his wife and madhy (pre-seminal fluid) is discharged from his private part, which is not "water of life" (i.e., not semen)? The Prophet Muhammad (peace and blessings be upon him) replied: He should wash his private part and perform ablution as for prayer.
