Narrated Abu Juhaifa: Allah's Messenger (ﷺ) came out at midday and offered a two-rak`at Zuhr and `Asr prayers at Al-Batha and a short spear (or stick) was planted in front of him (as a Sutra). He performed ablution and the people took the remaining water left after his ablution and rubbed their bodies with it.

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ أَبِي جُحَيْفَةَ، قَالَ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِالْهَاجِرَةِ فَصَلَّى بِالْبَطْحَاءِ الظُّهْرَ وَالْعَصْرَ رَكْعَتَيْنِ، وَنَصَبَ بَيْنَ يَدَيْهِ عَنَزَةً، وَتَوَضَّأَ، فَجَعَلَ النَّاسُ يَتَمَسَّحُونَ بِوَضُوئِهِ.
