حَدَّثَنَا مُوسَى، حَدَّثَنَا أَبُو عَوَانَةَ، حَدَّثَنَا طَارِقٌ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِيهِ، أَنَّهُ كَانَ مِمَّنْ بَايَعَ تَحْتَ الشَّجَرَةِ، فَرَجَعْنَا إِلَيْهَا الْعَامَ الْمُقْبِلَ فَعَمِيَتْ عَلَيْنَا.Narrated Sa`id bin Al-Musaiyab:That his father was amongst those who had given the Pledge of allegiance (to the Prophet (ﷺ) ) beneath the Tree, and the next year when they went towards the Tree, they were not able to recognize it
