Sahih Bukhari Volume 8, Book 78, Hadith 6151

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ أَتَى النَّبِيُّ صلى الله عليه وسلم عَلَى بَعْضِ نِسَائِهِ وَمَعَهُنَّ أُمُّ سُلَيْمٍ فَقَالَ ‏"‏ وَيْحَكَ يَا أَنْجَشَةُ، رُوَيْدَكَ سَوْقًا بِالْقَوَارِيرِ ‏"‏‏.‏ قَالَ أَبُو قِلاَبَةَ فَتَكَلَّمَ النَّبِيُّ صلى الله عليه وسلم بِكَلِمَةٍ، لَوْ تَكَلَّمَ بَعْضُكُمْ لَعِبْتُمُوهَا عَلَيْهِ قَوْلُهُ ‏"‏ سَوْقَكَ بِالْقَوَارِيرِ ‏"

Narrated By Anas bin Malik : The Prophet came to some of his wives among whom there was Um Sulaim, and said, "May Allah be merciful to you, O Anjasha! Drive the camels slowly, as they are carrying glass vessels!" Abu Qalaba said, "The Prophet said a sentence (i.e. the above metaphor) which, had anyone of you said it, you would have admonished him for it".
