Al-Adab Al-Mufrad, Book 33, Hadith 772 (English)

Anas reported that the Prophet, may Allah bless him and grant him peace, saw a man driving a sacrificial camel. "Ride it," he told him. The man replied, "It is a sacrificial camel." "Ride it," he repeated. The man said again, "It is a sacrificial camel." "Ride it," he repeated. The man said, "It is a sacrificial camel." The Prophet said, "Ride it, and bother you!"

حَدَّثَنَا مُوسَى، قَالَ‏:‏ حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى رَجُلاً يَسُوقُ بَدَنَةً، فَقَالَ‏:‏ ارْكَبْهَا، فَقَالَ‏:‏ إِنَّهَا بَدَنَةٌ، قَالَ‏:‏ ارْكَبْهَا، قَالَ‏:‏ إِنَّهَا بَدَنَةٌ، قَالَ‏:‏ ارْكَبْهَا، قَالَ‏:‏ فَإِنَّهَا بَدَنَةٌ، قَالَ‏:‏ ارْكَبْهَا، وَيْلَكَ‏.‏
