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.' "
