Ablutions (Wudu')
(What is said) about the urine of camels, sheep and other animals and about their folds
حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنَا أَبُو التَّيَّاحِ، يَزِيدُ بْنُ حُمَيْدٍ عَنْ أَنَسٍ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي قَبْلَ أَنْ يُبْنَى الْمَسْجِدُ فِي مَرَابِضِ الْغَنَمِ.
Narrated Anas: Prior to the construction of the mosque, the Prophet (ﷺ) offered the prayers at sheep-folds.
