Sahih Muslim 1322aBook 15, Hadith 412
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى رَجُلاً يَسُوقُ بَدَنَةً فَقَالَ " ارْكَبْهَا " . قَالَ يَا رَسُولَ اللَّهِ إِنَّهَا بَدَنَةٌ . فَقَالَ " ارْكَبْهَا وَيْلَكَ " . فِي الثَّانِيَةِ أَوْ فِي الثَّالِثَةِ .
Messenger of Allah, it is a sacrificial camel. He told him again to ride on it; (when he received the same reply) he said: Woe to you, (he uttered these words on the second or the third reply).
