أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ بْنِ عُتَيْبَةَ، قَالَ سَمِعْتُ أَبَا جُحَيْفَةَ، قَالَ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِالْهَاجِرَةِ - قَالَ ابْنُ الْمُثَنَّى إِلَى الْبَطْحَاءِ - فَتَوَضَّأَ وَصَلَّى الظُّهْرَ رَكْعَتَيْنِ وَالْعَصْرَ رَكْعَتَيْنِ وَبَيْنَ يَدَيْهِ عَنَزَةٌ ‏.‏

It was narrated that Al-Hakam bin 'Utaibah said: "I heard Abu Juhaifah say: 'The Messenger of Allah (PBUH) set off at midday, during the time of intense heat' - (One of the narrators) Ibn Al-Muthanna said, to Al-Batha' - and he performed Wudu', and prayed Zuhr, two Rak'ahs, and 'Asr, two Rak'ahs, with a short spear ('Anzah) in front of him.
