Sunan an-Nasa'i, Book 45, Hadith 110 (In-Book) ⓘ

It was narrated from 'Abdullah bin Mughaffal that he saw a man throwing pebbles and he said: "Do not throw pebbles, for the Prophet of Allah forbade throwing pebbles," or "he disliked the throwing of pebbles." Kahmas (one of the narrators) was not sure.

أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا يَزِيدُ، قَالَ أَنْبَأَنَا كَهْمَسٌ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ، أَنَّهُ رَأَى رَجُلاً يَخْذِفُ فَقَالَ لاَ تَخْذِفْ فَإِنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم كَانَ يَنْهَى عَنِ الْخَذْفِ أَوْ يَكْرَهُ الْخَذْفَ ‏.‏ شَكَّ كَهْمَسُ ‏.‏
