Al-Muwatta de Malik, 141

Yahia Ibn Sa'id a rapporté qu'un bédouin entra dans la mosquée, et voulant uriner, les gens s'écrièrent à haute voix (pour l'empêcher). L'Envoyé d'Allah (salallahou alayhi wa salam) r (Sur lui la grâce et la paix d'Allah) leur dit: «Laissez-le (terminer)». Le bédouin urina, et l'Envoyé d'Allah (salallahou alayhi wa salam) r (Sur lui la grâce et la paix d'Allah) fit apporter un seau d'eau et le versa sur la place souillée

Yahya related to me from Malik that Yahya ibn Said said, "A Bedouin came into the mosque and uncovered his private parts to urinate. The people called out to him and began to raise their voices but the Messenger of Allah, may Allah bless him and grant him peace, said ,'Let him be. 'So they let him be and he urinated. Then the Messenger of Allah, may Allah bless him and grant him peace, ordered a bucketful of water to be brought and it was poured on the place
