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 Ibn `Umar

The Prophet (ﷺ) said, "Wailakum" (woe to you) or "waihakum" (May Allah be merciful to you)." Shu`ba is not sure as to which was the right word. "Do not become disbelievers after me by cutting the necks of one another."
