Abu Hurairah said:The Messenger of Allah (SWAS)saw a man driving the sacrificial camel. He said ride on it. He said this is a sacrificial camel. He again said ride on it, bother you, either the second or the third time he spoke.
حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم رَأَى رَجُلاً يَسُوقُ بَدَنَةً . فَقَالَ " ارْكَبْهَا " . قَالَ إِنَّهَا بَدَنَةٌ . فَقَالَ " ارْكَبْهَا وَيْلَكَ " . فِي الثَّانِيَةِ أَوْ فِي الثَّالِثَةِ .
