Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "Someone who buys food, must not resell it until he takes delivery of it all".
The Prophet Muhammad, may Allah bless him and grant him peace, was a role model for all Muslims to follow; he taught us how to conduct ourselves in an ethical manner when dealing with others. He showed us how important it is to be honest and fair when conducting business transactions so as not to take advantage of anyone or cause any harm or distress. By following his teachings, we can ensure that our dealings are conducted ethically and fairly for everyone involved.
