Muwatta Malik #1027

Yahya related to me from Malik from Yahya ibn Said from Abdullah ibn al-Mughira ibn Abi Burda al-Kinani that he had heard that the Messenger of Allah, may Allah bless him and grant him peace, came to the people in their tribes and made dua for them, but left out one of the tribes. Abdullah related, "The tribe found an onyx necklace in the saddle-bags of one of their men. The Messenger of Allah, may Allah bless him and grant him peace, came to them, and then did the takbir over them as one does the takbir over the dead."
