The ruling on giving money to a person to trade with, where he keeps all the profit, on the condition that he returns the principal

Question:
He says: Honorable Shaykh, may Allah grant you success. A partner in a mudarabah (profit-sharing partnership) who works without capital, and over time earns money, is he allowed to dispense with the owner of the capital? Even if the owner of the capital does not agree?

Answer:
I did not understand the question. If you give money to a person to trade with, and all the profit is his, this is called a mudarabah. This is called a qard (loan). A qard is when you give money to someone you have affection for and feel compassion for. You give him money and say to him, “Work with this, make a profit for us, and return the principal to me later.” This is called a qard.
