عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا وَقَدْ سُئِلَ عَنْ رُكُوبِ الْهَدْيِ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ ارْكَبْهَا بِالْمَعْرُوفِ إِذَا أُلْجِئْتَ إِلَيْهَا حَتَّى تَجِدَ ظَهْرًا
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) was asked about riding the sacrificial animal. He said: I heard the Messenger of Allah (peace and blessings be upon him) say: If you are compelled, then ride it in a customary manner until you find another mount.
