This hadith is listed as number 4819 in Maktaba Shamila
وحَدَّثَنَاه حَامِدُ بْنُ عُمَرَ ، حَدَّثَنَا أَبُو عَوَانَةَ ، عَنْ طَارِقٍ ، عَنْ سَعِيدِ بْنِ الْمُسَيِّبِ ، قَالَ : كَانَ أَبِي مِمَّنْ بَايَعَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِنْدَ الشَّجَرَةِ ، قَالَ : " فَانْطَلَقْنَا فِي قَابِلٍ حَاجِّينَ فَخَفِيَ عَلَيْنَا مَكَانُهَا ، فَإِنْ كَانَتْ تَبَيَّنَتْ لَكُمْ فَأَنْتُمْ أَعْلَمُ " .
It has been narrated on the authority of Sa'id bin Musayyab who said: My father was one of those who swore fealty to the Messenger of Allah (ﷺ) near the tree. When we passed that way next year intending to perform the Hajj, the place of the tree was hidden to us. If you could point out clearly, you would (certainly) be knowing better. It has also been narrated on the authority of Sa'id bin Musayyib who learnt from his father that they were with the Messenger of Allah (ﷺ) in the year of the Tree (i. e. in the year of the fealty of God's pleasure sworn under the tree at Hudaibiya), but next year they forgot the spot of the tree.
