Sahih al-Bukhari Book 34, Hadith 31
The Prophet (ﷺ) said, "There was a merchant who used to lend the people, and whenever his debtor was in
straitened circumstances, he would say to his employees, 'Forgive him so that Allah may forgive us.'
So, Allah forgave him."
The Prophet (ﷺ) said, "Before your time the angels received the soul of a man and asked him, 'Did you do any good deeds (in your life)?' He replied, 'I used to order my employees to grant time to the rich person to pay his debts at his convenience.' So Allah said to the angels; "Excuse him." Rabi said that (the dead man said), 'I used to be easy to the rich and grant time to the poor.' Or, in another narration, 'grant time to the well-off and forgive the needy,' or, 'accept from the well-off and forgive the needy.'
Allah's Messenger (ﷺ) said, "The seller and the buyer have the right to keep or return goods as long as they have not parted or till they part; and if both the parties spoke the truth and described the defects and qualities (of the goods), then they would be blessed in their transaction, and if they told lies or hid something, then the blessings of their transaction would be lost."
