Narrated Anas bin Malik: Allah's Apostle visited a household among the Ansars, and he took a meal with them. When he intended to leave, he asked for a place in that house for him, to pray so a mat sprinkled with water was put and he offered prayer over it, and invoked for Allah's Blessing upon them (his hosts).
— Sahih Bukhari, Volume 8, Book 73: Good Manners and Form (Al-Adab), Hadith #103
