Sahih al-Bukhari 500
Sahih al-Bukhari · Book 8: Prayers (Salat) · To offer As-Salat (the prayer) using an 'Anaza (a spear-headed stick) (as a Sutra)
Narrated Anas Ibn Malik:
حَدَّثَنَا مُحَمَّدُ بْنُ حَاتِمِ بْنِ بَزِيعٍ ، قَالَ حَدَّثَنَا شَاذَانُ ، عَنْ شُعْبَةَ ، عَنْ عَطَاءِ بْنِ أَبِي مَيْمُونَةَ ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا خَرَجَ لِحَاجَتِهِ تَبِعْتُهُ أَنَا وَغُلاَمٌ وَمَعَنَا عُكَّازَةٌ أَوْ عَصًا أَوْ عَنَزَةٌ وَمَعَنَا إِدَاوَةٌ، فَإِذَا فَرَغَ مِنْ حَاجَتِهِ نَاوَلْنَاهُ الإِدَاوَةَ.
Whenever the Prophet (ﷺ) went for answering the call of nature, I and another boy used to go after him with a staff, a stick or a short spear (or stick) and a tumbler of water and when he finished from answering the call of nature we would hand that tumbler of water to him.
