The Prophet ﷺ as saying: The milk of milch camels may be drunk for payment when in pledge, and the animal may be ridden for payment when it is pledge; payment being made by the one who rides and the one who drinks. Abu Dawud said: In our opinion this is correct.
عَنِ النَّبِيِّ ﷺ قَالَ لَبَنُ الدَّرِّ يُحْلَبُ بِنَفَقَتِهِ إِذَا كَانَ مَرْهُونًا وَالظَّهْرُ يُرْكَبُ بِنَفَقَتِهِ إِذَا كَانَ مَرْهُونًا وَعَلَى الَّذِي يَرْكَبُ وَيَحْلِبُ النَّفَقَةُ
