Sahih al-Bukhari 778

It is related from Abu Qilaba that Malik ibn al-Huwayrith said to his companions, "Shall I tell you about the prayer of the Messenger of Allah, may Allah bless him and grant him peace?" Abu Qilaba said that it was not at the time of the prayer. He stood up and then did ruku' and said the takbir and raised his head and stood for a time and then went into sajda. He raised his head for a short time and prayed the same way as 'Amr ibn Salima, our Shaykh. (Ayyub said, "He used to do something which I did not see other people doing - he used to sit in the third and fourth rak'ats.") Malik said, "We came to the Prophet, may Allah bless him and grant him peace, and stayed with him. He said, 'If you return to your families, pray such and such a prayer at such and such a time and pray such and such a prayer at such and such a time. When it is time for the prayer, one of you should give the adhan and the oldest of you should be Imam."
