Saying "Wailaka."
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 ".
Narrated Anas: 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!"
