Messenger of Allah ﷺ came out at midday and offered a two-rakʿat Zuhr and ʿAsr 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.  

خَرَجَ رَسُولُ اللَّهِ ﷺ بِالْهَاجِرَةِ فَصَلَّى بِالْبَطْحَاءِ الظُّهْرَ وَالْعَصْرَ رَكْعَتَيْنِ وَنَصَبَ بَيْنَ يَدَيْهِ عَنَزَةً وَتَوَضَّأَ فَجَعَلَ النَّاسُ يَتَمَسَّحُونَ بِوَضُوئِهِ
