Refrain from haggling before sunrise; refrain from slaughtering animals that yield milk .

The Prophet Muhammad taught us to be mindful of our actions, even when it comes to buying and selling goods. He prohibited haggling before sunrise, as this is a time of peace and tranquility that should not be disturbed by the hustle and bustle of commerce. Additionally, he also forbade the slaughter of animals that yield milk, as these are essential for providing sustenance for people in need. These teachings remind us to be considerate in our dealings with others, especially those who are less fortunate than us.
