PROPHET MUHAMMAD (ﷺ) said:
May Allah's mercy be on him who is lenient in his buying, selling, and in demanding back his money.

PROPHET MUHAMMAD (ﷺ) said:
Whoever demands his rights let him do so in a decent manner as much as he can.

PROPHET MUHAMMAD (ﷺ) said:
There is no Muslim who lends something to another Muslim twice, but it will be like giving charity once.

PROPHET MUHAMMAD (ﷺ) said:
Whoever gives respite to one in difficulty, he will have (the reward of) an act of charity for each day. Whoever gives him respite after payment becomes due, will have (the reward of) an act of charity equal to (the amount of the loan) for each day.

PROPHET MUHAMMAD (ﷺ) said:
Whoever is easy with (a debtor) who is in difficulty, Allah will be easy with him in this world and in the Hereafter.

PROPHET MUHAMMAD (ﷺ) said:
Whoever would like Allah to shade him with His shade, let him give respite to one in difficulty, or waive repayment of the loan.

PROPHET MUHAMMAD (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.

PROPHET MUHAMMAD (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."

PROPHET MUHAMMAD (ﷺ) said:
"Once a man died and was asked, 'What did you use to say (or do) (in your life time)?' He replied, 'I was a businessman and used to give time to the rich to repay his debt and (used to) deduct part of the debt of the poor.' So he was forgiven (his sins.)"

PROPHET MUHAMMAD (ﷺ) said:
From among the people preceding your generation, there was a man whom the angel of death visited to capture his soul. (So his soul was captured) and he was asked if he had done any good deed.' He replied, 'I don't remember any good deed.' He was asked to think it over. He said, 'I do not remember, except that I used to trade with the people in the world and I used to give a respite to the rich and forgive the poor (among my debtors). So Allah made him enter Paradise.

Narrated Abu Huraira:
A man came to the Prophet (ﷺ) demanding his debts and behaved rudely. The companions of the Prophet (ﷺ) intended to harm him, but Allah's Messenger (ﷺ) said (to them), "Leave him, for the creditor (i.e. owner of a right) has the right to speak." Allah's Messenger (ﷺ) then said, "Give him a camel of the same age as that of his." The people said, "O Allah's Messenger (ﷺ)! There is only a camel that is older than his." Allah's Messenger (ﷺ) said, "Give (it to) him, for the best amongst you is he who pays the rights of others handsomely."

It was narrated that Abu Sa'eed Al-Khudri said:
“A Bedouin came to the Prophet (ﷺ) to ask him to pay back a debt that he owed him, and he spoke harshly, saying: 'I will make things difficult for you unless you repay me.' His Companions rebuked him and said: 'Woe to you, do you know who you are speaking to?' He said: 'I am only asking for my rights.' The Prophet (ﷺ) said: 'Why do you not support the one who has a right?' Then he sent word to Khawlah bint Qais, saying to her: 'If you have dates, lend them to us until our dates come, then we will pay you back.' She said: 'Yes, may my father be ransomed for you, O Messenger of Allah (ﷺ)!' So she gave him a loan, and he paid back the Bedouin and fed him. He (the Bedouin) said: 'You have paid me in full, may Allah (SWT) pay you in full.' He (the Prophet (ﷺ) ) said: 'Those are the best of people. May that nation not be cleansed (of sin) among whom the weak cannot get their rights without trouble.' ”

PROPHET MUHAMMAD (ﷺ) said:
If one who can afford it delays repayment, his honor and punishment become permissible.
