Sahih Muslim , Hadith 501 ⓘ
Ibn Umar reported: When the Messenger of Allah (may peace he upon him) went out on the 'Id day, he ordered to carry a spear-and it was fixed in front of him, and he said prayer towards its (direction), and the people were behind him. And he did it in the journey, and that is the reason why the Amirs carried it.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، ح وَحَدَّثَنَا ابْنُ نُمَيْرٍ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا أَبِي، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا خَرَجَ يَوْمَ الْعِيدِ أَمَرَ بِالْحَرْبَةِ فَتُوضَعُ بَيْنَ يَدَيْهِ فَيُصَلِّي إِلَيْهَا وَالنَّاسُ وَرَاءَهُ وَكَانَ يَفْعَلُ ذَلِكَ فِي السَّفَرِ فَمِنْ ثَمَّ اتَّخَذَهَا الأُمَرَاءُ .

Ibn Umar reported: The Apostle of Allah set up (sutra), and Abu Bakr said: He implanted iron-tipped spear and said prayer towards its direction. Ibn Abu Shaiba made this addition to it:" Ubaidullah said that it was a spear."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَابْنُ، نُمَيْرٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يَرْكُزُ - وَقَالَ أَبُو بَكْرٍ يَغْرِزُ - الْعَنَزَةَ وَيُصَلِّي إِلَيْهَا . زَادَ ابْنُ أَبِي شَيْبَةَ قَالَ عُبَيْدُ اللَّهِ وَهْىَ الْحَرْبَةُ .
