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