Narrated Aisha: The companions of Allah's Apostle used to practice manual labor, so their sweat used to smell, and they were advised to take a bath.

Narrated Al-Miqdam: The Prophet said, "Nobody has ever eaten a better meal than that which one has earned by working with one's own hands. The Prophet of Allah, David used to eat from the earnings of his manual labor."

Narrated Abu Huraira: Allah's Apostle said, "The Prophet David used not to eat except from the earnings of his manual labor."

Narrated Abu Huraira: Allah's Apostle said, "No doubt, it isbetter for any one of you to cut a bundle ofwood and carry it over his back rather than toask someone who may or may not givehim."

Narrated Az-Zubair bin Al-Awwam: The Prophet said, "One would rather take a rope and cut wood and carry it than ask others).

Narrated Jabir bin `Abdullah: Allah's Apostle said, "May Allah's mercy be on him who is lenient in his buying, selling, and in demanding back his money."

Narrated Hudhaifa: The Prophet 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.'

Narrated Abu Huraira: The Prophet 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."

And it is narrated from ‘Adā’ bin Khālid (may Allah be pleased with him) that he said: The Prophet (peace and blessings of Allah be upon him) wrote a contract of sale for me, stating:“This is the document in which Muhammad, the Messenger of Allah (peace and blessings of Allah be upon him), declares the purchase from ‘Adā’ bin Khālid. This is the sale of a Muslim to a Muslim. There is no defect in it, nor any deception, nor immorality, nor any evil intent.”And Qatādah (may Allah have mercy on him) said:“Ghā’ilah”refers to adultery, theft, and the habit of running away. Someone said to Ibrāhīm al-Nakha‘ī (may Allah have mercy on him) that some brokers name their stables“Ārī Khurāsān and Sijistān”(the Khurāsān stable and the Sijistān stable), and (to deceive) say:“Such-and-such an animal just arrived from Khurāsān yesterday,”and“Such-and-such just arrived from Sijistān today.”So Ibrāhīm al-Nakha‘ī heard this with great displeasure. ‘Uqbah bin ‘Āmir said:“It is not permissible for anyone to sell a commodity, knowing that it has a defect, without informing the buyer about it.”

Narrated Hakim bin Hizam: Allah's Apostle 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."
