Sahih al-Bukhari, Hadith 633 ⓘ
Narrated `Aun bin Abi Juhaifa: My father said, "I saw Allah's Messenger at a place called Al-Abtah. Bilal came and informed him about the prayer and then came out with a short spear (or stick) and planted it in front of Allah's Messenger at Al-Abtah and pronounced the Iqama."
حَدَّثَنَا إِسْحَاقُ، قَالَ أَخْبَرَنَا جَعْفَرُ بْنُ عَوْنٍ، قَالَ حَدَّثَنَا أَبُو الْعُمَيْسِ، عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ، عَنْ أَبِيهِ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم بِالأَبْطَحِ فَجَاءَهُ بِلاَلٌ فَآذَنَهُ بِالصَّلاَةِ، ثُمَّ خَرَجَ بِلاَلٌ بِالْعَنَزَةِ حَتَّى رَكَزَهَا بَيْنَ يَدَىْ رَسُولِ اللَّهِ صلى الله عليه وسلم بِالأَبْطَحِ وَأَقَامَ الصَّلاَةَ.
