Business Transactions
A narration by al-Bukhari has:
"An evil example does not apply to us, one who repossesses a gift is like a dog which vomits and then returns to its vomit."
وَفِي رِوَايَةٍ لِلْبُخَارِيِّ : { لَيْسَ لَنَا مَثَلُ اَلسَّوْءِ, اَلَّذِي يَعُودُ فِي هِبَتِهِ كَالْكَلْبِ يَرْجِعُ فِي قَيْئِهِ } 1‏ .‏
