Sahih al-Bukhari, Book 78, Hadith 187 (In-Book) ⓘ

Narrated Anas bin Malik: Allah's Messenger was on a journey and he had a black slave called Anjasha, and he was driving the camels (very fast, and there were women riding on those camels). Allah's Messenger said, "Waihaka (May Allah be merciful to you), O Anjasha! Drive slowly (the camels) with the glass vessels (women)!"

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ الْبُنَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ،‏.‏ وَأَيُّوبَ عَنْ أَبِي قِلاَبَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي سَفَرٍ، وَكَانَ مَعَهُ غُلاَمٌ لَهُ أَسْوَدُ، يُقَالُ لَهُ أَنْجَشَةُ، يَحْدُو، فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ وَيْحَكَ يَا أَنْجَشَةُ رُوَيْدَكَ بِالْقَوَارِيرِ ‏" ‏‏.‏
