حَدَّثَنَا أَسْوَدُ بْنُ عَامِرٍ أَخْبَرَنَا هُرَيْمٌ عَنْ عُبَيْدِ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ كَانَ رَسُولُ اللَّهِ تُحْمَلُ مَعَهُ الْعَنَزَةُ فِي الْعِيدَيْنِ فِي أَسْفَارِهِ فَتُرْكَزُ بَيْنَ يَدَيْهِ فَيُصَلِّي إِلَيْهَا
مسند امام احمد بن حنبل · Hadith 5734
It was narrated that Ibn 'Umar said: The Messenger of Allah (PBUH) used to carry a spear with him on the two Eids and on his journeys. He would set it up, then pray facing towards it.
