Narrated Zaid bin Khalid: I asked `Uthman bin `Affan about a person who engaged in intercourse but did no discharge. `Uthman replied, He should perform ablution like the one for an ordinary prayer but he must wash his penis. `Uthman added, I heard it from Allah's Apostle. I asked `Ali Az-Zubair, Talha and Ubai bin Ka`b about it and they, too, gave the same reply. (This order was canceled later on and taking a bath became necessary for such cases).
