Narrated Anas:
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ ، حَدَّثَنَا هَمَّامٌ ، عَنْ قَتَادَةَ ، عَنْ أَنَسٍ ـ رضى الله عنه أَنَّ النَّبِيَّ صلى الله عليه وسلم رَأَى رَجُلاً يَسُوقُ بَدَنَةً فَقَالَ " ارْكَبْهَا ". قَالَ إِنَّهَا بَدَنَةٌ. قَالَ " ارْكَبْهَا ". قَالَ إِنَّهَا بَدَنَةٌ. قَالَ " ارْكَبْهَا وَيْلَكَ " .
The Prophet (ﷺ) saw a man driving a Badana (a camel for sacrifice) and said (to him). "Ride it." The man said, "It is a Bandana." The Prophet (ﷺ) said, "Ride on it." The man said, "It is a Bandana." The Prophet (ﷺ) said, Ride on it, woe to you!"
