Narrated Anas bin Malik:

Allah's Apostle 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 Apostle ﷺ 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 ﷺ فِي سَفَرٍ، وَكَانَ مَعَهُ غُلاَمٌ لَهُ أَسْوَدُ، يُقَالُ لَهُ أَنْجَشَةُ، يَحْدُو، فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ " وَيْحَكَ يَا أَنْجَشَةُ رُوَيْدَكَ بِالْقَوَارِيرِ ".
