Muwatta Imam Malik Book of Jihad, Hadith 24
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 ﷺ 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 ﷺ came to them, and then did the takbir over them as one does the takbir over the dead."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَبْدِ اللَّهِ بْنِ الْمُغِيرَةِ بْنِ أَبِي بُرْدَةَ الْكِنَانِيِّ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى النَّاسَ فِي قَبَائِلِهِمْ يَدْعُو لَهُمْ وَأَنَّهُ تَرَكَ قَبِيلَةً مِنَ الْقَبَائِلِ - قَالَ - وَإِنَّ الْقَبِيلَةَ وَجَدُوا فِي بَرْدَعَةِ رَجُلٍ مِنْهُمْ عِقْدَ جَزْعٍ غُلُولاً فَأَتَاهُمْ رَسُولُ اللَّهِ ﷺ فَكَبَّرَ عَلَيْهِمْ كَمَا يُكَبِّرُ عَلَى الْمَيِّتِ .
