Be fair in dealings with others; Do not try to make extra profit at someone else's expense; Follow Islamic teachings; Respect people's rights; Respect other's property; Do not overcharge people for goods or services; Give people their due rights without any increase between them

This hadith is about the prohibition of taking more than the equivalent value for goods and services. It was narrated by Yahya from Malik from Humayd ibn Qays al-Makki that Mujahid said he was with Abdullah ibn Umar when an artisan came to him asking if it was permissible to take more money than what his work was worth. Abdullah forbade him from doing so and continued to forbid him until they reached the door of a mosque or an animal he intended to mount. Then Abdullah said that one should only take a dinar for a dinar and a dirham for a dirham without any increase between them as this is what our Prophet commanded us and our advice to you. This hadith teaches us that we should not take advantage of people by charging them more money than what their work or goods are worth as this goes against Islamic teachings. We should always be fair in our dealings with others and not try to make extra profit at their expense.
