Al-Muwatta de Malik, 110

Ata Ibn Yassar a rapporté que l'Envoyé d'Allah (salallahou alayhi wa salam) r (Sur lui la grâce et la paix d'Allah) au début de l'une de ses prières, après avoir fait le takbir, fit signe aux fidèles de garder leur place. Il partit et revint et on put remarquer les traces d'eau sur sa peau

Yahya related to me from Malik from Ismail ibn Abi Hakim that Ata ibn Yasar told him that the Messenger of Allah, may Allah bless him and grant him peace, said the takbir in one of the prayers and then indicated to them with his hand to stay in place. He left and then returned with traces of water on his skin
