"The Prophet borrowed forty thousand from me, then some wealth came to him, and he paid me back and said: 'May Allah bless your family and your wealth for you: the reward for lending is praise and repayment."  

اسْتَقْرَضَ مِنِّي النَّبِيُّ ﷺ أَرْبَعِينَ أَلْفًا فَجَاءَهُ مَالٌ فَدَفَعَهُ إِلَىَّ وَقَالَ بَارَكَ اللَّهُ لَكَ فِي أَهْلِكَ وَمَالِكَ إِنَّمَا جَزَاءُ السَّلَفِ الْحَمْدُ وَالأَدَاءُ  

the Prophet ﷺ borrowed thirty or forty thousand from him, when he fought at Hunain. When he came back he paid the loan, then the Prophet ﷺ said to him: 'May Allah (SWT) bless your family and your wealth for you. The reward for lending is repayment and words of paradise.”  

أَنَّ النَّبِيَّ ﷺ اسْتَسْلَفَ مِنْهُ حِينَ غَزَا حُنَيْنًا ثَلاَثِينَ أَوْ أَرْبَعِينَ أَلْفًا فَلَمَّا قَدِمَ قَضَاهَا إِيَّاهُ ثُمَّ قَالَ لَهُ النَّبِيُّ ﷺ بَارَكَ اللَّهُ لَكَ فِي أَهْلِكَ وَمَالِكَ إِنَّمَا جَزَاءُ السَّلَفِ الْوَفَاءُ وَالْحَمْدُ
