Call to Prayers (Adhaan)
Bukhari :: Book 1 :: Volume 11 :: Hadith 654
Narrated Itban bin Malik Al-Ansari:
The Prophet (came to my house and) asked permission for entering and I allowed him. He asked, "Where do you like me to pray in your house?" I pointed to a place which I liked. He stood up for prayer and we aligned behind him and he finished the prayer with Taslim and we did the same.
