Hadith 10:282
Sahl b. al-Hanzaliya told of God’s Messenger coming upon an emaciated camel and saying, “Fear God regarding these dumb animals. Ride them when they are in good condition and let them free when they are in good condition.” Abu Dawud transmitted it.
وَعَن سهلِ بنِ الحَنظلِيَّةِ قَالَ: مَرَّ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِبَعِيرٍ قَدْ لَحِقَ ظَهْرُهُ بِبَطْنِهِ فَقَالَ: «اتَّقُوا اللَّهَ فِي هَذِهِ الْبَهَائِمِ الْمُعْجَمَةِ فَارْكَبُوهَا صَالِحَة واترُكوها صَالِحَة» . رَوَاهُ أَبُو دَاوُد
