Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Saeed bin Huwairith that I heard Ibn Abbas (may Allah be pleased with them) say: We were present with the Noble Prophet (peace and blessings be upon him) when he returned from relieving himself, and food was brought to him. It was said to him: Why did you not perform ablution? The Prophet (peace and blessings be upon him) replied: "I do not have to pray, so why should I perform ablution?"

Hazrat Hisham narrates from his father that Hazrat Umar bin Khattab came out of the toilet and food was brought to him. The people said: We will bring water for ablution. Hazrat Umar said: I eat only with my right hand and use my left hand for cleaning myself. Thus, he ate the food without even touching the water.

Hazrat Salim bin Abi Al-Ja'd narrates from his father that Hazrat Ibn Mas'ud invited a man to eat with him, so the man said, "I have urinated." He (Ibn Mas'ud) replied, "You did not urinate on your hand."

Hazrat Salim bin Abi Al-Ja'd narrates from his father that Hazrat Abdullah invited a man to his food, so he replied, "I have just urinated and come." He (Hazrat Abdullah) said, "Your urine is not in your hand, is it?"
