عن أبي قتادة الأنصاري رضي الله عنه مرفوعاً: "لا يُمْسِكَنَّ أَحَدُكُم ذَكَره بَيمِينِه وهو يبول، ولا يَتَمَسَّحْ من الخلاء بيمينه، ولا يَتَنَفَّس في الإناء".
[صحيح] - [متفق عليه]
Abu Qatādah al-Ansāri (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "No one of you should hold his penis with his right hand while urinating, or clean himself after answering the call of nature using his right hand, or breathe into the vessel."
Sahih/Authentic. - [Al-Bukhari and Muslim]
The Prophet (may Allah's peace and blessings be upon him) commands the Muslim not to touch his penis with his right hand while urinating, nor to remove impurities from his anus or genitals with his right hand. He also forbids breathing into the container from which one is drinking because of the many harms that this entails.
