حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، حَدَّثَنِي عُتْبَةُ بْنُ حُمَيْدٍ الضَّبِّيُّ، عَنْ يَحْيَى بْنِ أَبِي إِسْحَاقَ الْهُنَائِيِّ، قَالَ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ الرَّجُلُ مِنَّا يُقْرِضُ أَخَاهُ الْمَالَ فَيُهْدِي لَهُ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِذَا أَقْرَضَ أَحَدُكُمْ قَرْضًا فَأَهْدَى لَهُ أَوْ حَمَلَهُ عَلَى الدَّابَّةِ فَلاَ يَرْكَبْهَا وَلاَ يَقْبَلْهُ إِلاَّ أَنْ يَكُونَ جَرَى بَيْنَهُ وَبَيْنَهُ قَبْلَ ذَلِكَ ‏"‏ ‏.‏

It was narrated that Yahya bin Abu Ishaq Al-Huna'i said: “I asked Anas bin Malik: 'What if a man gives his brother a loan, then (the borrower) give him a gift?’ The Messenger of Allah (PBUH) said: ‘If anyone of you borrow something then he gives (the lender) a gift or gives him a ride on his riding-beast, he should not accept the gift or the ride, unless they used to treat each other in that manner beforehand.'” Translation Not Available
