Narrated 'Uqba bin Sahban:

'Abdullah bin Mughaffal Al-Muzani who was one of those who witnessed (the event of) the tree, said, "The Prophet forbade the throwing of small stones (with two fingers)." 'Abdullah bin Al-Mughaffal Al-Muzani also said, "The Prophet also forbade urinating at the place where one takes a bath."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا شَبَابَةُ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ عُقْبَةَ بْنَ صُهْبَانَ، عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ الْمُزَنِيِّ، إِنِّي مِمَّنْ شَهِدَ الشَّجَرَةَ، نَهَى النَّبِيُّ ﷺ عَنِ الْخَذْفِ.
