Sahih al-Bukhari
Call to Prayers (Adhaan)
Chapter: The necessity of saying the Takbir, i.e., Allahu Akbar (Allah is the Most Great) and the commencement of As-Salat (the prayer)
Narrated Anas bin Malik:
Allah's Messenger (ﷺ) fell from a horse and got injured so he led the prayer sitting and we also prayed sitting. When he completed the prayer he said, "The Imam is to be followed; if he says Takbir then say Takbir, bow if he bows; raise your heads when he raises his head, when he says, 'Sami`a l-lahu liman hamidah say, 'Rabbana laka l-hamd', and prostrate when he prostrates."
Sahih al-Bukhari 733
