Mishkat al-Masabih, hadith 2757

وَعَنْ جَابِرٍ: أَنَّهُ كَانَ يَسِيرُ عَلَى جَمَلٍ لَهُ قد أعيي فَمَرَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِهِ فَضَرَبَهُ فَسَارَ سَيْرًا لَيْسَ يَسِيرُ مِثْلَهُ ثُمَّ قَالَ: «بِعْنِيهِ بِوُقِيَّةٍ» قَالَ: فَبِعْتُهُ فَاسْتَثْنَيْتُ حُمْلَانَهُ إِلَى أَهْلِي فَلَمَّا قَدِمْتُ الْمَدِينَةَ أَتَيْتُهُ بِالْجَمَلِ وَنَقَدَنِي ثَمَنَهُ وَفِي رِوَايَةٍ فَأَعْطَانِي ثَمَنَهُ وَرَدَّهُ عَلَيَّ. مُتَّفَقٌ عَلَيْهِ. وَفِي رِوَايَةٍ لِلْبُخَارِيِّ أَنَّهُ قَالَ لِبِلَالٍ: «اقْضِهِ وَزِدْهُ» فَأَعْطَاهُ وَزَادَهُ قِيرَاطًا

I was travelling on a camel of mine which had grown jaded when the Prophet passed by and struck it, with the result that it went as it had never done before. He then said, “Sell it to me for a wuqiya*”. I agreed, but made the stipulation that I should be allowed to ride it home. Then when I came to Medina I took the camel to him and he paid me its price in ready money. In a version he said, “He gave me its price and returned it to me." In a version by Bukhari he said to Bilal, “Pay him and give something extra," so he gave the money adding a qirat (A small coin, probably meaning here a sixteenth of a dirham). (Bukhari and Muslim.) *This and the more common form uqiya used below in the tradition from 'A'isha is an amount equivalent to forty dirhams.
