Mortgaging
48/4. Chapter:
To mortgage an animal used for riding or milking
وَقَالَ مُغِيرَةُ عَنْ إِبْرَاهِيمَ تُرْكَبُ الضَّالَّةُ بِقَدْرِ عَلَفِهَا، وَتُحْلَبُ بِقَدْرِ عَلَفِهَا، وَالرَّهْنُ مِثْلُهُ.Mughira narrated that Ibrahim said: One can ride and milk the lost animal in proportion to the amount of food one gives to it; this is valid also for mortgaged animals.
Sahih Bukhari
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا زَكَرِيَّاءُ، عَنْ عَامِرٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ يَقُولُ " الرَّهْنُ يُرْكَبُ بِنَفَقَتِهِ، وَيُشْرَبُ لَبَنُ الدَّرِّ إِذَا كَانَ مَرْهُونًا ".
Narrated Abu Huraira: The Prophet (ﷺ) said, "One can ride the mortgaged animal because of what one spends on it, and one can drink the milk of a milch animal as long as it is mortgaged. "
