“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.' ”
Sunan Ibn Majah Book 15, Hadith 37
Allah's Messenger (ﷺ) said, "The first batch (of people) who will enter Paradise will be (glittering) like a full
moon; and those who will enter next will be (glittering) like the brightest star. Their hearts will be as if
the heart of a single man, for they will have no enmity amongst themselves, and everyone of them
shall have two wives, each of whom will be so beautiful, pure and transparent that the marrow of the
bones of their legs will be seen through the flesh. They will be glorifying Allah in the morning and
evening, and will never fall ill, and they will neither blow their noses, nor spit. Their utensils will be
of gold and silver, and their combs will be of gold, and the fuel used in their centers will be the aloeswood,
and their sweat will smell like musk."
Sahih al-Bukhari Book 59, Hadith 57
Malik spoke about what was done among them in the case of a group
of people who bought goods, drapery or slaves, and a man heard about
it and said to one of the group, "I have heard the description and
situation of the drapery goods you bought from so-and-so. Shall I give
you such-and-such profit to take over your portion?" This person
agreed, and the man gave him the profit and became a partner in his
place. When he looked at the purchase, he saw that it was ugly and
found it too expensive.
Malik said, "It is obliged on him and
there is no choice in it for him if he bought it according to a list
of contents and the description was well-known."
Malik spoke
about a man who had drapery goods sent to him, and salesmen came to
him and he read to them his list of contents and said, "In each bag is
such-and-such a wrap from Basra and such-and-such a light wrap from
Sabir. Their size is such-and-such," and he named to them types of
drapery goods by their sort, and he said, "Buy them from me according
to this description." They bought the bags according to what he
described to them, and then they bought them and found them too
expensive and regretted it. Malik said, "The sale is binding on them,
if the goods agree with the list of contents on which he sold them."
Malik said, "This is the way of doing things which people
still use today. They permit the sale among them when the goods agree
with the list of contents and are not different from it. "
