Chapter: The prohibition of cleaning oneself with the right hand

The Messenger of Allah (ﷺ) said: None of you should hold penis with his right hand while urinating, or wipe himself with his right hand in privy and should not breathe into the vessel (from which he drinks).

When anyone amongst you enters the privy he should not touch his penis with his right hand.

The Messenger of Allah (way peace be upon him) forbade (us) to breathe into the venel, to touch the penis with the right hand and to wipe after relieving with right hand.
