The aforesaid tradition has also been transmitted by ‘Ubaid bin ‘ Umair through a different chain of narrators. This version goes:A man asked: Messenger of Allah (ﷺ), what is due on camels? He replied in a similar way. This version adds "and to lend its udders.”
حَدَّثَنَا يَحْيَى بْنُ خَلَفٍ، حَدَّثَنَا أَبُو عَاصِمٍ، عَنِ ابْنِ جُرَيْجٍ، قَالَ قَالَ أَبُو الزُّبَيْرِ سَمِعْتُ عُبَيْدَ بْنَ عُمَيْرٍ، قَالَ قَالَ رَجُلٌ يَا رَسُولَ اللَّهِ مَا حَقُّ الإِبِلِ فَذَكَرَ نَحْوَهُ زَادَ " وَإِعَارَةُ دَلْوِهَا " .
