Is it permissible for someone who has entered into a transaction to withdraw with a specific profit percentage before its completion?

Question:
I have the other part, Shaykh. If I, for example, entered into a commercial matter with people and we put in a certain amount and entered into a commercial transaction, is it permissible for me, before the transaction ends, to withdraw with a specific profit percentage? I take my capital and a specific profit that I am satisfied with and withdraw before the specified period ends.

Answer:
No, you take your capital and withdraw if you want to withdraw, but taking a profit when you have not yet calculated and known the profit is not permissible, yes.
