"‏ إِنَّ فُلاَنًا أَهْدَى إِلَىَّ نَاقَةً فَعَوَّضْتُهُ مِنْهَا سِتَّ بَكَرَاتٍ فَظَلَّ سَاخِطًا وَلَقَدْ هَمَمْتُ أَنْ لاَ أَقْبَلَ هَدِيَّةً إِلاَّ مِنْ قُرَشِيٍّ أَوْ أَنْصَارِيٍّ أَوْ ثَقَفِيٍّ أَوْ دَوْسِيٍّ ‏"

that a Bedouin gave a young female camel as a gift to the Messenger of Allah (ﷺ), so he in turn for that, gave him six young female camels. But he was not satisfied with that, so when that news reached the Prophet (ﷺ), he praised Allah, and expressed gratitude to Him, then said: 'Indeed so-and-so gave a camel to me as a gift, so I reciprocated for that with six young she-camels, yet he became upset. So I decided that I would not accept a gift except from a Quraishi, or Ansari, or Dawsi.'"
