Narrated Abdullah ibn Amr ibn al-'As:

When we went out along with the Messenger of Allah ﷺ to at-Ta'if we passed a grave. I heard the Messenger of Allah ﷺ say: This is the grave of AbuRighal. He was in this sacred mosque (sanctuary) protecting himself (from punishment). When he came out, he suffered the same punishment which his people suffered at this place, and he was buried in it. The sign of it is that a golden bough was buried with him. If you dig it out, you will find it with him. The people hastened to it and took out the bough.

حَدَّثَنَا يَحْيَى بْنُ مَعِينٍ، حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا أَبِي، سَمِعْتُ مُحَمَّدَ بْنَ إِسْحَاقَ، يُحَدِّثُ عَنْ إِسْمَاعِيلَ بْنِ أُمَيَّةَ، عَنْ بُجَيْرِ بْنِ أَبِي بُجَيْرٍ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَمْرٍو، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ حِينَ خَرَجْنَا مَعَهُ إِلَى الطَّائِفِ فَمَرَرْنَا بِقَبْرٍ فَقَالَ رَسُولُ اللَّهِ ﷺ
" هَذَا قَبْرُ أَبِي رِغَالٍ وَكَانَ بِهَذَا الْحَرَمِ يَدْفَعُ عَنْهُ فَلَمَّا خَرَجَ أَصَابَتْهُ النِّقْمَةُ الَّتِي أَصَابَتْ قَوْمَهُ بِهَذَا الْمَكَانِ فَدُفِنَ فِيهِ وَآيَةُ ذَلِكَ أَنَّهُ دُفِنَ مَعَهُ غُصْنٌ مِنْ ذَهَبٍ إِنْ أَنْتُمْ نَبَشْتُمْ عَنْهُ أَصَبْتُمُوهُ مَعَهُ " . فَابْتَدَرَهُ النَّاسُ فَاسْتَخْرَجُوا الْغُصْنَ .
